Instructions for using the esbe three-way valve. Three-way valve working principle

The ESBE three-way valve is just one of the elements of the life support systems of a residential building. On the one hand, this is a simple design. On the other hand, it performs an important task in engineering networks. Demand creates supply. There are many models on the market from different manufacturers. Three-way valves manufactured under the ESBE brand are distinguished by good performance.

Some useful knowledge

Three-way butterfly valve ESBE

The three-way valve is a control device in piping systems with a liquid working medium. In simple terms, built into the design of the heating network, it will act like a well-known mixer tap that switches or mixes flows. Installing the valve allows you to solve a number of practical problems:

• Redirection of flows coming from different pipelines.
• Achieving the desired temperature of the working fluid by mixing hot and cold flow.
• Obtaining a jet with a constant temperature by dynamic redirection.

Complicated? Only at first glance. In order to understand the principle of operation of the device, consider its design features.

Design

A three-way mixing valve has a control element, which is a stem or a ball. The rod moves vertically, the ball moves around its axis. Since the movement of the regulating element does not allow to completely block the flow of the working fluid, it is mixed and redistributed. The simplest models are an ordinary crane. Their main advantage is low cost and constructive simplicity. The disadvantage is the impossibility of stabilizing the outlet temperature. Despite the shortcomings, the tap can be installed in underfloor heating systems. Now imagine a motorized valve. This design is already more functional, as it is able to regulate the temperature automatically. A simple valve is a balancing valve. Its main function is to adjust the section for the passage of the work stream. Conventionally, the principle of its operation can be described as follows:

• The handle is turned by 50% - uniform mixing of the two streams, since the inlet valves will be equal.
• The handle is turned 100% - the first valve is fully pressed and blocks the movement of the fluid flow.

The modifications presented on the market may have different handle turns, but the principle of their operation is preserved. The valve and its position are adjusted manually, thereby ensuring a balance between the two streams.

Kinds

There are several types of such devices:

• With hydraulic drive.
• With pneumatic drive.
• With electric drive.

A motorized three-way valve, such as the ESBE model, will have a slightly different operating principle. The electric drive performs the function of a conventional thermostat, which makes it possible not only to mix the flows, but to maintain the set temperature. When the temperature drops / rises, the drive automatically changes the position of the shut-off valves, increasing or decreasing the cross section of the hot water flow. At the same time, the cross section at the cold flow inlet also changes. The result is water with a constant temperature. The ESBE crane does not require any human intervention. Its work is regulated by automation.

Valve principle

Equipped with electric actuators and thermostats, ESBE valves are equally well suited for use in heating and hot water systems. In principle, the valve can be installed in any pipeline where it is necessary to mix two fluid streams with a constant temperature. No matter how high-quality and reliable a three-way valve with a thermostat is, it will have one drawback that is characteristic of absolutely all devices of this type.

Such a disadvantage is the strong narrowing of the entry points. The narrowed section of the entry point, in turn, increases the hydraulic resistance.

Such a faucet will work well in water supply systems. ESBE dampers are suitable for installation in underfloor heating systems, but a special wiring diagram is required. In addition to the designs described above, three-way thermostatic valves are on the market. These devices are often confused with each other, but still they are completely different. Thermostatic models have a thermostat with a remote sensor, but they differ not only in this element, but also in the principle of operation. Unlike conventional models, in thermostatic taps, the flow is regulated only at one point, the remaining two are open, and their cross section does not change. When choosing such a design, you need to check if there is narrowness at point 2, otherwise the hydraulic resistance will lead to difficulties in the operation of the device. It may be necessary to install a mixing valve in an alternative ring to minimize the problem.

Wiring diagrams

Three-way valve - switching circuit

Almost all three-way valves on the market are connected in the same way. Consider it on the example of ESBE cranes. Let's start with water supply systems, since the mixer tap is used most often here. The main purpose for which the valve is installed is to reduce the risk of backflow. Between the two streams - with cold and hot water - there will inevitably be a pressure drop. It can lead to reverse flow. When installing ESBE valves, such incidents are rare. In heating systems, ESBE valves are used only in three directions:

• In mixing units of "warm floor" type systems.
• To stabilize the temperature of the liquid flow in the inlet pipeline of the boiler.
• To reduce the supply of high temperature coolant from the boiler to the pipeline.

Valve in the mixing unit

Consider how the ESBE crane is used in underfloor heating systems. The mixing unit creates an additional circuit in the system. It is connected to the distribution manifold at two points, which ensures constant circulation of the liquid at the outlet. At the inlet, the flow is provided only if additional heat is needed. A valve with a thermostat is connected to the mixing unit. Since at point 2 all valves, including the ESBE, are narrowed, insufficient pump flow can be observed. To increase it, a second line is being created, which makes it possible to reduce the consumption of electricity by pumping equipment. The second line is not always required. Some models of three-way valves have sufficient orifice.

Scheme of a warm floor with a three-way valve

In the event that there is insufficient flow power on the first line, the thermostat will not be able to open the passage to the required value . The problem is easily solved in two ways: narrowing the second line or installing a balancing valve on it. The second way is more productive. It allows you to fine-tune the flow. You can connect a three-way valve according to another scheme that does not require the installation of a balancing valve. For this, pumping equipment is connected to the second line. As a result, the temperature of the inlet and outlet streams is compared. A thermostatic valve can be installed in systems with a single circuit. The simplest example of such systems is underfloor heating in small rooms. Creating a mixing node here , with its large size , is not always justified. It is better to connect a warm floor with one circuit. A three-way valve with a thermostat is installed on the return line, through which the already cooled coolant flows. In this case, the thermostat will move the shut-off valves, increasing the cross section and opening the flow. After heating the pipe, the temperature sensor reads the data and reduces the flow.

For heating boilers

Three-way valves for heating boilers should be considered separately. The main task of their installation is to prevent a cold flow of coolant to the incoming pipeline connected to the boiler. Otherwise, condensation will begin to form on the pipes, and temperature changes in the system will lead to its deformation at the joints. There is no need to talk about the consequences of such deformations. At best, a small leak forms, at worst, the system will have to be completely changed.

Three-way valve in the heating system

It is especially important to connect shutoff valves to solid fuel boilers, which are characterized by significant temperature differences during operation. Connecting the mixing valve allows you to ensure that no liquid enters the inlet of the boiler equipment, the temperature of which is below 50 degrees. As a result, the temperature difference decreases, the negative impact of cold with all the ensuing consequences is reduced. It is recommended to install mixing valves in systems with plastic piping. Here the goal is to prevent high temperature coolant from entering the pipeline. With all the advantages of polymers, they do not withstand the frequent increase in temperatures above operating parameters. Under such operating conditions, the pipeline is rapidly destroyed. Temperature indicators recommended by experts range from 75 to 85 degrees. The installation of valves solves many problems, but the model must be selected exactly according to the technical characteristics of the utility network, and must have sufficient passage.

Conclusion

The simplest shut-off valves - three-way mixing valves - are an important element of engineering communications. Modern models, created at the junction of old traditions and modern technologies, have made it possible to achieve excellent results of their use for a variety of purposes.

In a wide range of valves used for heating systems, there is an element that is used quite rarely. Its shape resembles a tee, although the functions it performs are completely different. We are talking about a three-way valve, the principle of operation of which will be discussed in this article.

The principle of operation of the three-way valve

What is this device, why is it needed at all?

How it works

The three-way valve is mounted on those sections of the pipelines where it is required to divide the flow of the circulating fluid into 2 circuits:

• with variable hydraulic regime;
• with constant.

In most cases, a constant flow is required for those for whom a liquid of high quality and in the indicated volumes is supplied. It is regulated in accordance with the quality indicators. As for the variable flow, it is used for objects where quality indicators are not the main ones. There, the quantity factor is of great importance. Simply put, the supply of coolant there is carried out according to the required amount.

Note! The shut-off valve also includes an analogue of the device described in the article - a two-way valve. How is it different? The fact is that the three-way option works on a completely different principle. The rod included in its design is unable to block the flow of fluid, which has constant hydraulic performance.

The stem is open all the time, it is adjusted to one or another volume of liquid. Consequently, users will be able to get the volume they need, both in terms of quantity and quality. In general, this device is unable to stop the supply of liquid to a network in which the hydraulic flow is constant. At the same time, it may well block the flow of a variable type, due to which, in fact, it becomes possible to adjust the flow / pressure.

And if you connect a pair of two-way type devices, you can get one, but three-way. But it is necessary that both work on the reverse, in other words, when one valve is closed, the next one should open.

Valve classification

Without lengthy introductions, we note that the device can be of two types according to the principle of operation. It can be:

• separating;
• mixing.

Features of the action of each type are already clear from their name. The mixing device consists of two outlets and an inlet. In other words, it is necessary for mixing fluid flows, which may be required in order to reduce its temperature. By the way, this is the best option for setting the desired mode in the "warm floor".

The procedure for adjusting the temperature regime is extremely simple. You just need to know about the current temperature indicators of the incoming fluid flows, accurately calculate the required proportions of each of them so that you get the desired indicators at the output. By the way, this device, subject to proper installation and adjustment, can also function for flow separation.

But the dividing valve divides one flow in two, therefore, it is equipped with one inlet and two outlets. This device is mainly used to separate the flow of hot water in DHW systems. Although quite often it is also found in the piping of air heaters.

Outwardly, both options are almost identical. But if you look at their drawing in section, then their main difference is immediately visible. The stem, which is installed in the mixing type device, has one ball valve. It is located in the center and blocks the main passage.

As for separating devices, in them the stem has two such valves, which are installed at the outlets. They function according to the following principle: one of them is pressed against the saddle, closing the passage, and the other simultaneously opens passage No. 2.

According to the management method, modern models can be:

• electric;
• manual.

In most cases, a hand-held device is used, which looks like an ordinary ball valve, but is equipped with three outlet pipes. But electric models with automatic control are used mainly in private homes, namely in order to distribute heat. For example, the user can set the temperature regime by room, and the working fluid will flow in accordance with the distance of the room from the heater. As an option - you can combine it with a "warm floor".

Video - Device in the boiler group

Three-way valves, as well as other devices, are defined according to the system pressure and inlet diameter. All this is regulated by GOST. And if the requirements of the latter are not met, this will be regarded as a gross violation, especially when it comes to the pressure indicator in the line.

Applications

The three-way valve, the principle of operation of which was discussed above, has a fairly wide scope. So, its varieties, such as an electromagnetic device or a device with a thermal head, are often found in modern highways, where it is necessary to adjust the proportions when mixing two separated liquid streams, but without reducing power or volume.

As for domestic use, the most popular here is a thermostatic mixing device, with which, as noted above, you can adjust the temperature of the working fluid. This liquid can be supplied both to the "warm floor" pipeline and to heating radiators. And if the valve also has automatic control, then it will be possible to control the temperature in the home without any problems!

Note! The use of a three-way valve in a heating system in order to balance temperature differences is extremely beneficial not only in terms of comfort and convenience, but also in terms of cost savings.

The fact is that by regulating the temperature of the liquid on the "return" of the heater, it is possible to significantly reduce the amount of fuel consumed, and this will have a positive effect on the efficiency of the system itself. In some systems, a valve is simply necessary. For example, in a "warm floor" system, this device prevents the floor covering from overheating above a given comfort level, thereby relieving users of discomfort.

Control devices of this kind are also used in water supply systems in order to obtain a permanent flow at the required temperature. The simplest example is an ordinary faucet, where you can make water hot/cooler by opening/closing a cold faucet.

Adjusting the flow of the working fluid. What to look for when buying?

Manual adjustment is made by means of a conventional ball valve. Visually, it is very similar to a simple valve, but has an additional outlet. Armature of this kind is used for forced manual control.

As for automatic adjustment, a special three-way valve is used here, equipped with an electromechanical device for changing the position of the stem. It should be connected to a thermostat in order to be able to adjust the temperature in the room.

Remember that when buying a valve, it is imperative to take into account the technical parameters of the device, which include the following.

• Diameter of connection to the heating main. Often this indicator varies from 2 to 4 centimeters, although much depends on the characteristics of the system itself. If the device of a suitable diameter could not be found, then you will have to use special adapters.
• The possibility of installing a servo drive on a three-way valve, the principle of operation is considered at the beginning of the article. Thanks to this, the device will be able to work automatically. This moment is very important if the device is selected for operation in "warm floors" of the water type.
• Finally, this is the throughput of the pipeline. This concept refers to the volume of liquid that can pass through it in a certain time.

Popular manufacturers

There are many manufacturers of three-way valves on the domestic market. The choice of a particular model depends primarily on:

• type of mechanism (and, we recall, it can be mechanical or electrical);
• areas of use (DHW, cold water, "warm floor", heating).

The most popular device is considered to be Esbe is a Swedish valve from a company that has been around for over a hundred years. This is a reliable, high-quality and durable product that has proven itself in many areas. Combination of European quality and modern technologies.

Another popular model is the American Honeywell - a true brainchild of high technology. Simple operation, convenience and comfort, compactness and reliability are the distinguishing features of these valves.

Finally, relatively "young", but promising devices are valves of the Valtec line - the result of a joint collaboration between Italian and Russian engineers. All products are of high quality, sold with a warranty period of seven years. They differ in that they have a very affordable price.

How to install a mixing valve with your own hands

This installation scheme is used mainly in boiler rooms of those heating systems that are connected to a hydraulic separator or to a non-pressure collector. And the pump located in circuit No. 2 provides the required circulation of the working fluid.

Note! If the three-way valve will be connected directly to a bypass heat source connected to port B, then a valve with a hydraulic resistance equal to the same resistance of this source will also be required.

If this is not done, then the flow rate of the working fluid in the segment A-B will fluctuate in accordance with the movement of the rod. We also note that this installation scheme provides for the possible termination of the circulation of liquid through the source, if the installation was carried out without a circulation pump or a hydraulic separator in the main circuit.

It is undesirable to connect the valve to heating networks or a pressure manifold in the absence of devices that throttle excessive pressure. Otherwise, the flow rate of the liquid in the section A-B will fluctuate, and significantly.

If overheating of the return is allowed, excessive pressure is eliminated by means of a jumper installed in parallel to the valve admixture in the circuit.

How to install a dividing valve with your own hands

Providing quantitative adjustment by changing the flow of fluid is the main function that such a three-way valve performs. The principle of its operation is extremely simple and has been discussed above. It is used where it is possible to bypass the liquid to the "return", and the termination of circulation, on the contrary, is not allowed.

Note! This connection scheme has gained wide popularity in water and air heating units that are connected from individual boiler houses.

In order to link the hydraulic circuits, it is necessary that the pressure loss of the consumer be equal to the loss on the balancing valve in the bypass. The diagram shown here is intended for installation on those pipelines in which there is excessive pressure. The liquid in this case moves due to the strong pressure generated by the circulation pump.

Video - Three-way valve and its principle of operation

Despite the simple design, the esbe three-way valve is one of those elements on which the life support of the whole house directly depends. Devices of this type are commercially available in several varieties.

general information

A three-way valve is a device for adjusting pipeline networks with a liquid working medium. If you explain popularly, after being included in the heating system, the device will perform the function of a well-known mixer tap, the task of which is to switch or mix flows.

Thanks to the esbe three-way valve, the following results are achieved:

1. Redirecting streams from different networks.
2. The working fluid is brought to the required temperature by mixing cold and hot fluids.
3. Dynamic redirection makes it possible to obtain a jet of stable temperature.

Design features of the ESBE three-way valve

The adjustment of the three-way valve is carried out using a stem or ball. In the first case, the adjusting element moves in the vertical direction, in the second - around its axis. This element moves in such a way that a complete blockage of the flow of the working fluid does not occur: it only mixes and redirects. The simplest example of such a device is a conventional crane. Its strong point is its simple design and low cost; weak - the impossibility of obtaining a stable outlet temperature. For all their shortcomings, taps are widely used in underfloor heating systems.

If an electric drive is introduced into the design of a conventional crane, then it will be possible to significantly increase its functionality: the device will be able to regulate the temperature of the liquid medium in automatic mode. The task of simple balancing valves is to adjust the section for the flow of the working flow.

The device works like this:

1. When the handle is turned halfway, the two streams are evenly mixed, which is ensured by the equality of the inlet valves.
2. If the handle is turned all the way, the first valve will be pressed, due to which the liquid flow is completely blocked.

For commercially available models, the turns of the handles may differ slightly, which in no way affects the principle of operation of the devices.

Main varieties

Three-way valves are of three types:

• Hydraulic.
• Electric.
• Pneumatic.

Motorized appliances (eg model ESBE) differ slightly in their principle of operation. An electric appendage acts here like a conventional thermostat: thanks to it, the flows are not only mixed, but also kept at the desired temperature. During a decrease or increase in temperature, the position of the shut-off valves is automatically changed. As a result, the flow cross section increases or decreases. In parallel, there is a change in the cross section at the inlet of the cold flow, which makes it possible to inform the water at the outlet of a stable temperature. At the same time, the three-way esbe valve completely dispenses with human control: the equipment is controlled by automation.

The ESBE valve with electric actuator and thermostat can be successfully used in heating systems and in hot water supply. Strictly speaking, such a valve can be equipped with any type of pipeline, where it is required to mix two liquid streams and maintain a stable temperature. Even the most high-quality and reliable models of a three-way valve with a thermostat have one common drawback for products of this type: the entry points through which fluid enters are very narrowed. As a consequence, this provokes an increase in hydraulic resistance.

These faucets are great for plumbing. ESBE valves are often equipped with underfloor heating, although they use a special connection scheme. Along with the modifications mentioned above, three-way thermostatic valves can be found on sale. Despite the apparent similarity of these devices, their functions differ in many ways. In thermostatic varieties, thermostats with a remote type sensor are used. In addition, the principle of operation here is also different.

Unlike standard models, thermostatic taps control the flow at only one point. The other two inputs are in a permanently open position, with a stable section. When purchasing such a design, it is important to test the second point for narrowness, otherwise the device may experience difficulties due to high hydraulic resistance. If such a defect is found, the problem can be solved by installing a mixing valve in an additional circuit.

ESBE tap connection principle

For the vast majority of commercially available three-way devices, one connection scheme is used. For example, consider installing an esbe three-way valve. It's best to start with the plumbing system, where mixing taps are most common. Valves in this case prevent the formation of backflow. The fact is that cold and hot streams have different pressures, which provokes drops. As a result, reverse flow may occur. Systems with ESBE valves are completely safe in this respect.

In heating systems, only three sections can be equipped with devices of this type:

• Mixers of the "warm floor" system.
• The pipe entering the boiler. Thus, stabilization of the temperature of the coolant in the incoming pipeline is achieved.
• Outlet pipe, to reduce the supply of heated coolant.

mixing unit

The use of the esbe valve for underfloor heating has its own specifics. The location of the mixing unit is an additional circuit. Switching with the manifold is carried out through two points: this allows the inlet coolant to constantly circulate. The inlet flow is opened only when there is a need for additional heat.

The mixing unit is commutated with a valve and a thermostat. You need to understand that a thermostat for a water-heated floor allows you to reduce heating costs. Given the narrowness of all valves at point 2, the pump may be faced with the problem of insufficient flow. To solve the problem, it is necessary to live the second line, which reduces the level of electricity consumption. But such a need does not always arise, because. the cross section of some three-way valves is quite large.

In a situation where the first line has insufficient flow capacity, the thermostat does not block the passage on the required scale.

To get out of this situation, two options are usually used:

1. The second line is narrowing.
2. The balancing valve is installed.

The second method is considered more effective, because. the flow in this case is tuned more precisely. There is another scheme for connecting the esbe three-way valve for underfloor heating - switching the pump to the second line: a balancing valve is not needed here. This allows you to equalize the temperature regime in the inlet and outlet streams.

Installation of a valve with a thermostat can be carried out in single-circuit systems. Their simplest variation is a warm floor of a small area. In this case, the overall mixing unit is not very practical to use. A more appropriate solution would be to connect a single-circuit underfloor heating. The installation of a three-way valve with a thermostat is carried out on a return pipe containing a cooled coolant. Thanks to the thermostat, the shut-off valve is activated, which increases the cross section. When the pipe heats up, the temperature sensor detects this and reduces the flow.

Application of valves for heating boilers

Three-way valves for heating boilers deserve special attention. They perform the task of preventing the cooled coolant from getting inside the pipeline entering the boiler. If this is not done, the pipes will begin to become covered with condensate, and a dangerous temperature difference will occur in the system. This is fraught with deformations of the docking sections, the most harmless consequence of which will be the appearance of small leaks. If you do not respond in time, the system may completely fail.

With particular responsibility, one should take the installation of shut-off valves in the piping of a solid fuel boiler, during which significant temperature differences occur (read also: ""). The mixing valve allows you to protect boiler equipment from the ingress of coolant with a temperature below +50 degrees. In this way, a reduction in the temperature difference is achieved, which has a positive effect on the efficiency and durability of the system.

Experts recommend using mixing valves also in systems with plastic piping. Although polymer communications have a number of advantages, however, the frequent excess of operating temperature parameters affects them destructively. According to the standards, the most comfortable temperature regime is in the range of + 75-85 degrees. Valves protect plastic pipes from many negative consequences. The selection of a device model must be taken responsibly, taking into account the technical characteristics of the engineering network.

Esbe products are quite popular today. is no exception. It is one of the many elements that are included in residential buildings.

The need to use

This design, on the one hand, is quite simple, but on the other hand, it is designed to perform an extremely important task, being part of engineering networks. Everyone knows the rule that demand creates supply, which is why on the market today you can find many models that are represented by various manufacturers. However, valves manufactured by Esbe are distinguished by excellent performance. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.

Design features

In a wide range today you can find Esbe products. The three-way valve is no exception. This element has a regulating component, which is a ball or a rod. The latter moves vertically, but as for the ball, its movement occurs around its axis. Due to the fact that the movements of the regulating element do not allow to block the flow of liquid, distribution and mixing occurs. The most common and simple models are cranes.

Main plus

Their main advantage is low cost and simplicity. However, if you need to adjust the Esbe three-way valve, then you should exclude the purchase of simple devices, since they have the main drawback, expressed in the inability to stabilize the outlet temperature.

Carrying out installation work

Almost all described valves that are on the market are connected on the basis of one scheme. Most often, mixer taps are used in water supply systems. Their main goal is to reduce the risk of backflow. Between the streams of cold and hot water, a pressure difference will inevitably occur. It can cause reverse flow. If you install a valve, then you will not encounter such a problem. If we are talking about a heating system, then such devices are used exclusively in three directions, namely, to stabilize the temperature regime of the coolant flow in the incoming pipeline of boiler equipment, to reduce the supply of high-temperature water from the heating device to the pipeline, as well as in the conditions of mixing units of systems underfloor heating.

Connection in the mixing unit

If you are interested in Esbe products, the three-way valve can be purchased from any relevant store. One has only to consider before that how the tap is used in the underfloor heating system. Application allows you to create an additional circuit in the system. It connects with two points to this allows for a constant circulation of water at the outlet. As for the inlet, the flow is provided only if there is a need to obtain additional heat. The thermostatic valve is connected to the mixing unit. Due to the fact that all valves are at the point, they are narrowed, which can cause insufficient flow of pumping equipment. To increase it, it is necessary to create an additional line, with which you can reduce the electricity consumption of the pump. During the installation process, it is worth remembering that a second line is not always required. A number of valve models have a fairly large passage. An Esbe three-way valve, whose connection diagram can be designed based on the instructions presented in the article, may suggest insufficient flow capacity in the first line. In this case, the thermostat is not able to open the passage of the required size. This issue can be easily solved in two ways: the first involves narrowing the second line, while the other option is to mount on it. The latter option is considered more productive, as it allows you to adjust the flow.

Alternative installation option

Installation of the Esbe three-way valve can also be done by another method. It does not involve the use of a balancing crane. The pump is connected to the second line, eventually the temperature of the outlet and inlet streams equalize. A thermostatic valve is found in single circuit systems. The simplest example of such systems is underfloor heating in small rooms. In this case, it is not always justified to create a mixing unit with large dimensions. It is best to connect the underfloor heating system using one circuit. If you are thinking about how to connect an Esbe three-way valve with an electric drive, then it can be placed on the return line, through which cooled water runs. In this case, the thermostat will lead to the movement of the valves, the cross section will be increased, and the flow will be open. As soon as the pipe is heated, the thermal sensor will detect this and reduce the flow.

Installation of a valve for a heating boiler

This issue, according to professionals, must be considered separately. The main task of the installation is to prevent the entry of a cold water flow to the incoming pipeline, which is connected to the heating equipment. If this requirement is not taken into account, then condensation will occur on the pipes, temperature drops will lead to deformation at the joints. If we talk about the consequences of deformation, then at best you will encounter a small leak, while at worst the system will need to be completely changed. In order to avoid the need to repair the Esbe three-way valve, it is important to connect the shut-off valves to the boiler, which is characterized by temperature changes during operation. If you install a mixing valve, then you can ensure that water does not enter the inlet of the equipment, the temperature of which is below 50 degrees. The temperature difference is significantly reduced, the negative impact of cold is reduced. Experts advise supplementing systems that are equipped with plastic pipelines with mixing valves. In this case, the task is to prevent the ingress of high temperature water into the pipeline. While polymers have many advantages, they do not do well with frequent temperature changes, which can be higher than operating temperatures.

Under the influence of such conditions, the pipeline system fails soon enough. Experts advise choosing Esbe products. The three-way valve, the installation instructions for which are presented in the article, has been manufactured by this company for a long time. If you use this element, then you can provide temperature readings ranging from 75 to 85 degrees, which are recommended by experts. Mounting the valve allows you to cope with many problems, however, the model must be selected in accordance with the characteristics of the network, and also have a sufficiently large passage.

Adjustment features

When purchasing Esbe products - a three-way valve, the installation and adjustment instructions for which are presented in the article - you must remember that with this device it is possible to mix the cooled water from the return into the supply. For high-quality regulation, not only a three-way valve, but also a four-way valve, which must be present in the heating system, is installed in the system independently. It is located directly in front of the contour of the warm floor. The handle allows you to open the bypass, while the circulation pumps and equipment draw in the cooled coolant from the return, where it is mixed with hot water. In order for the adjustment to be made as efficiently as possible, you should understand what happens at certain positions of the handle. The latter can be set to the bypass overlap position, while the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is blocked, water enters the tank and runs in a small circle. The third position allows you to feed the supply from the return system without blocking the full cycle of water passage throughout the circuit.

Conclusion

Recently, experts have increasingly recommended purchasing Esbe brand products. A three-way valve, the instruction, the wiring diagram of which is presented in the article, is just an example of this. It can act as an indispensable element of the heating system and part of the boiler equipment, however, it is important to choose the right model and install it, observing the technology.

Esbe valves are one of the most reliable and functional components used in various water supply systems, including domestic and main ones. It has a very wide range, which includes: rotary vrg131, dn25, as well as other popular varieties.

Currently, a three-way rotary sample of such equipment can be installed in every home. In order to do it right, let's look at the intricacies of working with such equipment and the features of its use.

Esbe valves - technical features of devices

Esbe valves are a variety of devices used to control a liquid or gas when it is supplied from one pipe to another. The three-way type of valves is distinguished by the presence of three connections that allow you to effectively redirect the flows in the system, especially in the case of mixing hot and cold water.

Adjusting the operation of valves of this type within the same system can realize the servo. This device needs a little more attention.

Servo. This is a separate element in the system that controls the position of the valves. A servo drive is usually the most affordable and easy to install, which is why it is most often used for.

According to the design features, the servo drive can be different, most often they are included in the category of such devices. For example, this can be installed with vrg131 samples. Today they provide the highest quality and accuracy in system maintenance, which is why they are so popular among consumers.

In some devices, a servo drive, as well as motor control is not used. In such cases, such special devices are used as for adjusting the operation of the equipment.

Such varieties include, for example, a dn25 valve, which can be mounted in a crane without a drive.

Appointment of Esbe valves

This type of product can be used in a wide range of systems, including heating systems, even centralized, hot, cold water supply, as well as air conditioning.

These types of valves are suitable for various systems, including those operating on oil products, gas, as well as eco-fuels, including solar energy or wind energy. It is possible to install these types of equipment, for example, a three-way rotary valve vrg131, both for central water supply networks and for home networks.

You can pick up a product for any crane. It is only important to choose the right type of product and install it according to the recommendations. Also, for the system to work properly, it is very important to adjust the servomotor or thermostatic controller.

Then the model chosen by you will work without failures, irrespective of the set technical parameters.

Advantages of using this type of valves

Among the main advantages of installing exactly Esbe products are:

1. Ease of installation of this type of components, the ability to install samples in virtually any system.
2. Wide operating temperature range, especially for models such as the vrg131 swivel crane.
3. Versatility in use - can be used in networks with different loads.
4. No need for maintenance of such samples with the correct installation of such equipment.
5. Can be used with any Esbe actuator that has the required specifications.
6. The presence in some details of the so-called burn protection functions- automatic shutdown of hot water supply in the event that cold water has ceased to flow into the system.

Popular models of Esbe valves

Currently, the following Esbe valve models are especially popular on sale:

• VTA200 equipment is the best faucet for all water supply systems. Applicable for systems without hot water recirculation, as well as HWC with this function. Does not require special maintenance;
• VTA270 is a model range suitable for installation in underfloor heating systems. They can be mounted in systems where there is no risk of “burning”. Suitable for systems with a fairly large area - up to 100 square meters;
• VTA310 is an equipment, like the vrg131 swivel tap, suitable for all water supply systems where there are no special requirements for protection against burns. Designed for areas with a maximum coolant temperature of 95 degrees, withstand a differential pressure of 0.3 MPa. This type of valve can be mounted in a crane with any type of actuator;
• VTA330/VTA360 - equipment that is installed in systems that do not have additional devices that carry out temperature control. The features of this equipment are that, like the 3-way valve vrg131, it reacts as sensitively as possible to changes in pressure in the system and allows you to maintain a stable water temperature even with its jumps. This model comes with a special protective cover, unless, of course, the user has chosen a different package. Parts of the VTA330/VTA360 are only distinguishable by the direction of the water flow;

• VTC300 is a thermostatic mixer. The crane is used for installation with boilers up to 30 kW. It is used in cases where a coolant of a sufficiently low temperature enters through the return pipe of the equipment. There is no need to install a servo drive for this model - without it, it also functions quite normally. The equipment has several installation options and can be easily adapted to the requirements of your chosen system;
• DN25 is another particularly popular valve model. Represents. Can also be used to protect boilers power up to 150 kW. The working temperature of this sample is also 110 degrees. DN25 is completely unpretentious to the installation conditions, its efficiency does not depend on the chosen installation position;
• model vrg131 - designed specifically for use in hot water networks. Released vrg from a specialized brass alloy, which significantly increases its service life. Can be set manually. It is recommended to use a servomotor from the same manufacturer to control this three-way valve.

Esbe products are quite popular today. is no exception. It is one of the many elements that are included in the life support system of residential buildings.

The need to use

This design, on the one hand, is quite simple, but on the other hand, it is designed to perform an extremely important task, being part of engineering networks. Everyone knows the rule that demand creates supply, which is why on the market today you can find many models that are represented by various manufacturers. However, valves manufactured by Esbe are distinguished by excellent performance. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.

Design features

In a wide range today you can find Esbe products. The three-way valve is no exception. This element has a regulating component, which is a ball or a rod. The latter moves vertically, but as for the ball, its movement occurs around its axis. Due to the fact that the movements of the regulating element do not allow to block the flow of liquid, distribution and mixing occurs. The most common and simple models are cranes.

Main plus

Their main advantage is low cost and simplicity. However, if you need to adjust the Esbe three-way valve, then you should exclude the purchase of simple devices, since they have the main drawback, expressed in the inability to stabilize the outlet temperature.

Carrying out installation work

Almost all described valves that are on the market are connected on the basis of one scheme. Most often, mixer taps are used in water supply systems. Their main goal is to reduce the risk of backflow. Between the streams of cold and hot water, a pressure difference will inevitably occur. It can cause reverse flow. If you install a valve, then you will not encounter such a problem. If we are talking about a heating system, then such devices are used exclusively in three directions, namely, to stabilize the temperature regime of the coolant flow in the incoming pipeline of boiler equipment, to reduce the supply of high-temperature water from the heating device to the pipeline, as well as in the conditions of mixing units of systems underfloor heating.

Connection in the mixing unit

If you are interested in Esbe products, the three-way valve can be purchased from any relevant store. One has only to consider before that how the tap is used in the underfloor heating system. The use of a mixing unit allows you to create an additional circuit in the system. It connects with two points to this allows for a constant circulation of water at the outlet. As for the inlet, the flow is provided only if there is a need to obtain additional heat. The thermostatic valve is connected to the mixing unit. Due to the fact that all valves are at the point, they are narrowed, which can cause insufficient flow of pumping equipment. To increase it, it is necessary to create an additional line, with which you can reduce the electricity consumption of the pump. During the installation process, it is worth remembering that a second line is not always required. A number of valve models have a fairly large passage. An Esbe three-way valve, whose connection diagram can be designed based on the instructions presented in the article, may suggest insufficient flow capacity in the first line. In this case, the thermostat is not able to open the passage of the required size. This issue can be easily solved in two ways: the first involves narrowing the second line, while the other option is to mount on it. The latter option is considered more productive, as it allows you to adjust the flow.

Alternative installation option

Installation of the Esbe three-way valve can also be done by another method. It does not involve the use of a balancing crane. The pump is connected to the second line, eventually the temperature of the outlet and inlet streams equalize. A thermostatic valve is found in single circuit systems. The simplest example of such systems is underfloor heating in small rooms. In this case, it is not always justified to create a mixing unit with large dimensions. It is best to connect the underfloor heating system using one circuit. If you are thinking about how to connect an Esbe three-way valve with an electric drive, then it can be placed on the return line, through which cooled water runs. In this case, the thermostat will lead to the movement of the valves, the cross section will be increased, and the flow will be open. As soon as the pipe is heated, the thermal sensor will detect this and reduce the flow.

Installation of a valve for a heating boiler

This issue, according to professionals, must be considered separately. The main task of the installation is to prevent the entry of a cold water flow to the incoming pipeline, which is connected to the heating equipment. If this requirement is not taken into account, then condensation will occur on the pipes, temperature drops will lead to deformation at the joints. If we talk about the consequences of deformation, then at best you will encounter a small leak, while at worst the system will need to be completely changed. In order to avoid the need to repair the Esbe three-way valve, it is important to connect the shut-off valves to the boiler, which is characterized by temperature changes during operation. If you install a mixing valve, then you can ensure that water does not enter the inlet of the equipment, the temperature of which is below 50 degrees. The temperature difference is significantly reduced, the negative impact of cold is reduced. Experts advise supplementing systems that are equipped with plastic pipelines with mixing valves. In this case, the task is to prevent the ingress of high temperature water into the pipeline. While polymers have many advantages, they do not do well with frequent temperature changes, which can be higher than operating temperatures.

Under the influence of such conditions, the pipeline system fails soon enough. Experts advise choosing Esbe products. The three-way valve, the installation instructions for which are presented in the article, has been manufactured by this company for a long time. If you use this element, then you can provide temperature readings ranging from 75 to 85 degrees, which are recommended by experts. Mounting the valve allows you to cope with many problems, however, the model must be selected in accordance with the characteristics of the network, and also have a sufficiently large passage.

Adjustment features

When purchasing Esbe products - a three-way valve, the installation and adjustment instructions for which are presented in the article - you must remember that with this device it is possible to mix the cooled water from the return into the supply. For high-quality regulation, not only a three-way valve, but also a four-way valve, which must be present in the heating system, is installed in the system independently. It is located directly in front of the contour of the warm floor. The handle allows you to open the bypass, while the circulation pumps and equipment draw in the cooled coolant from the return, where it is mixed with hot water. In order for the adjustment to be made as efficiently as possible, you should understand what happens at certain positions of the handle. The latter can be set to the bypass overlap position, while the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is blocked, water enters the tank and runs in a small circle. The third position allows you to feed the supply from the return system without blocking the full cycle of water passage throughout the circuit.

Conclusion

Recently, experts have increasingly recommended purchasing Esbe brand products. A three-way valve, the instruction, the wiring diagram of which is presented in the article, is just an example of this. It can act as an indispensable element of the heating system and part of the boiler equipment, however, it is important to choose the right model and install it, observing the technology.

A three-way valve in a water supply or heating system is responsible for mixing or separating liquids of different temperatures, as well as for obtaining the required temperature at the outlet of the liquid (adjusting the temperature of the coolant using a servo drive).

Design features

The body of the device contains two inlets and one outlet for liquids and a control element, which can be of different designs (for example, a rotary ball or a travel rod), as well as a place for a servo drive.

Usually, the valve is not designed to completely shut off the liquid outlet, but is only capable of controlling the mixing ratio of the liquids and the temperature in the system. The instruction does not imply, but functionally, it is quite possible to shut off the liquid supply.

A three-way valve of a certain variety, which performs a dividing function, may have a rotary servo to redirect the flow to different pipes (then it is called "shut-off").

In this case, there is no gradual or smooth mixing of fluids with temperature control, and the rotary mechanism itself consists of a ball (like a Bugatti ball valve).

There are several varieties of it, according to the type of drive mechanism, performing the same functions:

• Hydraulic slewing drive;
• Pneumatic drive;
• Electric servo.

Yes, three Esbe's new valve, having a servo drive, will assume the actual sample itself and a compatible drive manufactured by the same company.

Types and differences

Esbe has been in business for over 100 years and specializes in temperature control for hydraulic systems in small buildings.

It manufactures a valve and a rotary actuator for cooling or heating systems, also working "in conjunction" with indoor and outdoor temperature sensors in the system. The principle of operation of the Esbe three-way valve is similar to the above options.

The company produces several model series of three-way valves, including a mixing valve:

• Rotary valves (series models: VRG130, VRG330, 3F, H, VRH130, HG);
• Linear valves (series models: VLF300, VLF200, VLE132);
• Thermostatic mixing valve (series models: VTA and VTS).

Rotary valves

Valves of the VRG130 series are applied to systems of hot/cold water supply. This model range, like the subsequent ones, has various options (for example, the three-way valve from Esbe VRG 131 also belongs to this series and has a connection for a servo drive).

They are compact mixing models made of brass alloys, designed to minimize leakage and with a manual adjustment dial. The instruction indicates that they are also compatible with Esbe automatic control systems and controllers, which allow automating the operation of valves.

Esbe three-way valve of this model series - available in sizes DN 15-50, pressure class - PN 10, model options include varieties with internal (three-way mixing valve type Esbe model VRG131 with connection for actuator), external thread

(model VRG132), with union nut or compression fittings.

three-way Esbe's VRG330 Series Mixing Valve has similar features to the previously described VRG131 Series (DN 20-50, PN 10), but is specifically designed for high flows (60 percent kvs difference between inlets).

It can also be equipped with compatible controllers and automatic control. Available with three types of connection: internal thread, external thread, rotating nut.

According to Esbe specification, 3F series rotary mixing valves are designed for heating and cooling applications.

Esbe controllers and automatic control systems can also be used with them.

For ease of installation, the Esbe 3F three-way valve is marked with an adjustment scale on both sides. The valve body is made of cast iron, the model is also supplied with an adapter for a flanged pipe PN 6, model sizes - DN25-150.

The mixing valve from Esbe series H (DN25-40) and HG (DN25) is designed for installation in confined spaces.

This three-way control valve from Esbe is used only for heating systems and is specified for operation with a boiler group (made of cast iron, special "H"-shaped body). It also has an acceptable price.

As the main type of connection, both internal thread and its mixed type are used. Compatible with Esbe controllers and actuators like VRG131 .

Models of the VRH130 series are also made in the "H"-shaped version, but made of brass with a pressure class of PN 10. This model is more versatile than the previous sample and can also be used in water supply systems, is available with different body widths.

Line valves

The VLF300 series is a 3-way mixing line with sizes DN 15-50.

This model range is It is made of nodular cast iron and can be used with working fluids such as cold/hot water, and which contain antifreeze components (glycol, for example).

In the latter case, the sample must be equipped with a rod heater. It is completed with a flange for a PN 6 pipe. Models similar to those previously indicated, VLF200 dn25, are distinguished by a high working pressure of up to 16 bar (against 6 bar for the previously indicated model range).

Models VLE132 - made of bronze with sizes DN 15-50. These are linear motorized valves, which, like the previously mentioned similar models, can use water with glycol as working fluids (connection - external thread PN16), unlike the VRG131 series. Its price ranges from 140 to 350 euros.

All listed 3-way in-line valves are compatible with the Esbe controller and actuator.

thermostatic mixing valve

VTS520 / 550 - the instruction indicates that the three-way valves are designed to work with hot water systems that are connected to a solar heating system. Its price starts from 150 euros.

A feature of this model range is that the Esbe three-way thermostatic valve comes with specialized protection against burns, since the liquid circulating in the system is of a sufficiently high temperature.

Esbe's three-way thermostatic mixing valve with "scald protection" features a sensor that automatically turns off the hot water servo if cold water is not supplied.

The coolant with which these models work is water (including drinking water), the coolant of closed systems is water with non-freezing components. Pressure class - PN 10, the body is made of brass, resistant to corrosion, for example, the VRG131 valve is not suitable for such a system.

VTA330/530 is Esbe's thermostatic mixing valve of this series designed for use in domestic hot water systems, as well as in faucets or showers where no other means of temperature control is provided (VTA330), or in domestic hot water systems with high flow (VTA530). Its price is within 150 euros.

Also equipped with a security system you from burns. Pressure class PN 10 (material - brass, resistant to corrosion), is available with external threaded connection, fittings or adapters.

VTA360/560 - a series similar to the previous one, but equipped with a large number of fittings and connections. The instruction assumes that the drive of the Esbe three-way device of this series must also be compatible with those specified by the company in the specification.

Representatives of the VTA320/520 series can be used both in conditions similar to the operating modes of the previous model ranges, and in systems where other temperature control systems are present.

These valves are recommended for hot water circulation systems (HWC) or underfloor heating systems. Also equipped with "burn protection". VTA370 / 570 - models designed for use in the "warm floor" system, have a high throughput.

VTA310 - sample supplied with adjusting knob, without burn protection system. It is used in domestic water supply systems, including - in the system of hot water supply of a closed cycle (HWC). The price for it starts from 50 euros.

Installation features and prices

When installing a three-way mixing valve, various options, instructions and algorithms are selected for installation. As a rule, the part is not installed directly to the heat source, since the system uses a non-pressure manifold or "hydraulic arrowhead".

In the version for heating, the simplified instruction assumes that the coolant is supplied from the boiler to the valve, from there the coolant is fed into the heating system through the pump.

The liquid that has passed through the heating system and cooled down is sent to the boiler for heating, but also to the mixing valve, which ensures the temperature control of the supplied substance.

The instruction for the Esbe three-way valve usually involves a description of the connection of the valve to the system, which, depending on the model range, may be different.

The cw602n Esbe three-way valve (brass brand is indicated here) of the VRG130 model range (namely, VRG131 ½) costs an average of $ 170 (if purchased complete with an actuator).

The price of a three-way valve from Esbe linear VLA330, depending on the configuration, is $ 150 (not equipped with an electric actuator).

The Esbe three-way thermostatic valve (VTA 320) can be priced at $70 or more.
