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. The 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 the category of such devices includes. 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.

Three way mixing valve has a fairly simple device. It consists of a housing with two inlets and one outlet, as well as a specially shaped stem, on which a handle (for manual control) or an electric drive (for automatic flow temperature control) is installed. The rod is able to rotate along the vertical axis, blocking to some extent the inlet of hot or cold water, due to which a certain ratio of flows is created and, as a result, a mixture of a given temperature is obtained at the outlet. The body material of a three-way valve is most often brass alloy or cast iron. The stem is made of brass, cast iron or stainless steel.

Three way valve control is carried out with the help of an electric drive installed on the rod, which is supplied separately. The main characteristics of electric actuators are: the time of rotation of the rod by 90 degrees; the force with which the actuator is able to rotate the stem; electrical voltage and control signal (two-point, three-point, proportional). The electric drive receives a signal from the common house controller, which, based on the readings of various temperature sensors, calculates the position of the three-way valve stem to obtain the desired temperature of the coolant at the outlet.

Selecting an actuator for a rotary three-way mixing valve. For sleeve mixing valves ESBE actuators of the ARA600 series are used, for flanged cast iron valves the ESBE 90 series is used. If as a mixer, then 3-point control or proportional control is necessary: ​​0-10V signal. Next, select the desired combination of stem rotation time and valve assignment. 60 seconds will be enough for domestic hot water supply, and for supplying coolant to radiators, most often, electric drives with a stem rotation time of 120 seconds are used. If it is necessary to control external equipment depending on the position of the valve (for example, turn off an unnecessary pump, etc.), we determine whether an auxiliary switch is needed. When all the technical characteristics of the electric drive are determined, it will not be difficult to choose from the presented models exactly the one that will perform all the specified functions.

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 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.

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 in execution, 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 floor 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 closed cycle hot water supply system (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 arrow".

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 supplied to 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 (here the brand of brass is indicated) 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.

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 is installed in the system, but also a four-way valve, which must be present in the heating system. 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.

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 special 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.
