Esbe valves - technical features of devices
Esbe valves are types of devices used to regulate liquid or gas when it is supplied from one pipe to another. The three-way type of valves is characterized by the presence of three connections, which allow you to effectively redirect flows in the system, especially in the case of mixing hot and cold water.
Adjusting valve operation of this typewithin one system can carry out servo drive. This device needs to be given 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 readily available and easy to install, which is why it is most often used.
By design features The servo drive can be different, most often included in the category of such devices. For example, this can be installed with vrg131 samples. They give today 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 Electrical adjustment is not used. In such cases, the following applies special devices as for adjusting the operation of equipment.
These varieties include, for example, the dn25 valve, which can be mounted in a faucet without a drive.
Review of Esbe three-way valve (video)
Purpose of Esbe valves
This type of product can be used in a wide range of systems, including heating systems, even centralized, hot and 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. You can install these types of equipment, for example, a three-way rotary valve vrg131, as for networks central water supply, and for home networks.
You can select a product for any tap. It is only important to choose the right type of product and install it according to the recommendations. It is also very important to adjust the servo drive or thermostatic regulator for the system to operate properly.
Then the model you choose will work without failures, regardless of the specified technical parameters.
The advantages of using this particular type of valve
Among the main advantages of installing Esbe products are:
- Easy to install this type of component, the ability to install samples in virtually any system.
- Wide operating temperature range, especially for models such as the vrg131 rotary valve.
- Versatility in application - can be used in networks with different loads.
- There is no need to maintain such samples if such equipment is installed correctly.
- Can be used with any Esbe drive that has the required technical characteristics.
- The presence in some parts of the so-called Anti-scald functions– automatic shutdown of hot water supply if cold water stops flowing into the system.
Popular Esbe valve models
Currently, the following models of Esbe valves are especially popular on sale:
- VTA200 equipment is the best tap for all water supply systems. Suitable for systems without recirculation hot water, as well as HWCs that have this function. Do not require special maintenance;
- VTA270 is a model range suitable for installation in underfloor heating systems. They can be installed in systems where there is no risk of “burning”. Suitable for systems with fairly large area– up to 100 square meters;
- VTA310 is a piece of equipment, like the vrg131 rotary valve, suitable for all water supply systems that do not have special requirements for protection against burns. Designed for areas with a maximum coolant temperature of 95 degrees, withstand differential pressure of 0.3 MPa. This type the valves can be mounted in a faucet with any type of drive;
- VTA330/VTA360 is equipment that is installed in systems that do not have additional devices for temperature control. The peculiarities of this equipment are that it, like the 3-way faucet vrg131, reacts as sensitively as possible to changes in pressure in the system and allows you to maintain a stable water temperature even during pressure surges. This model comes with a special protective cover, unless, of course, the user has chosen a different package. Parts VTA330/VTA360 are distinguishable only by the direction of water flow;
- VTC300 – thermostatic mixer. The crane is used for installation with boilers with a power of up to 30 kW. It is used in cases where coolant at a sufficiently low temperature flows 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 the system you choose;
- DN25 is another particularly popular valve model. Represents. Also suitable for protecting boilers power up to 150 kW. The operating temperature of this sample is also 110 degrees. DN25 is completely unpretentious to installation conditions, its operating efficiency does not depend on the chosen installation position;
- model vrg131 - designed directly for use in hot water supply networks. The vrg is made from a specialized brass alloy, which significantly increases its service life. Can be installed manually. It is recommended to use a servo drive 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.
Need for use
This design, on the one hand, is quite simple, but on the other, 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 all kinds of manufacturers. However, valves produced by Esbe have excellent performance characteristics. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.
Design features
Today you can find a wide range of Esbe products. The three-way valve is no exception. This element has a regulating component, which is a ball or 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 control element do not allow the flow of liquid to be blocked, distribution and mixing occurs. The most common and simple models are cranes.
Main advantage
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 simple devices, since they have the main disadvantage expressed in the lack of the ability to stabilize temperature regime at the exit.
Carrying out installation work
Almost all of the described valves that are on the market are connected based on the same circuit. Mixing taps are most often used in water supply systems. Their main goal is to reduce the risk of backflow. There will inevitably be a pressure difference between the cold and hot water flows. It may cause backflow. If you install a valve, 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 like a warm floor.
Connection in the mixing unit
If you are interested in Esbe products, you can purchase a three-way valve at any relevant store. One has only to first consider how the faucet is used in a heated floor system. The use of a mixing unit allows you to create an additional circuit in the system. It is connected to two points, which allows for constant circulation of water at the outlet. As for the input, the flow is provided only if there is a need to obtain additional heat. A valve with a thermostat is connected to the mixing unit. Due to the fact that all the valves are located at the point, they are narrowed, which can cause insufficient flow of the 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 bore. The Esbe three-way valve, the connection diagram of which can be developed based on the instructions presented in the article, may suggest insufficient flow power 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 resolved in two ways: the first involves narrowing the second line, while the other option is to install it on it. The latter option is considered more productive, as it allows you to adjust the flow.
Alternative option for installation work
The Esbe three-way valve can be installed using another method. It does not involve the use balancing valve. The pump is connected to the second line, ultimately the temperature of the output and input streams is equalized. The faucet with thermostat is located in systems with one circuit. The simplest example of such systems is heated floors in small rooms. In this case, it is not always justified to create a mixing unit with large dimensions. It would be best to connect the underfloor heating system using one circuit. If you are wondering how to connect three-way valve Esbe with an electric drive, it can be placed on the return line through which cooled water runs. In this case, the thermostat will cause the shut-off valves to move, the cross-section will be increased, and the flow will be open. As soon as the pipe is heated, the temperature 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 installation is to prevent the entry of cold water flow into the incoming pipeline, which is connected to heating equipment. If this requirement is not taken into account, condensation will form on the pipes, and temperature changes will lead to deformation at the joint points. If we talk about the consequences of deformation, then best case scenario you will encounter a small leak, while at worst the system will need to be completely replaced. In order to avoid the need for repair of 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, you can ensure that water with a temperature below 50 degrees does not enter the equipment inlet. Temperature differences are significantly reduced, negative impact the cold is decreasing. Experts advise supplementing systems that use plastic pipelines with mixing valves. In this case, the task is to prevent water from entering the pipeline from high temperature. Despite the fact that polymers have many advantages, they do not cope well with frequent temperature changes that may be higher than operating temperatures.
When exposed to such conditions, the pipeline system soon fails. 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, you will be able to provide temperature readings ranging from 75 to 85 degrees, which are recommended by experts. Installing a valve can solve many problems, but 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, installation and adjustment instructions for which are presented in the article - you must remember that with the help of this device it is possible to mix cooled water from the return to the supply. For high-quality regulation, not only a three-way valve is installed in the system, but also four way valve, which must be present in the heating system. It is placed directly in front of the heated floor circuit. The handle allows you to open the bypass, while circulation pumps and equipment draw cooled coolant from the return, where it mixes with hot water. In order for the adjustment to be made as efficiently as possible, you need to understand what happens at certain positions of the handle. The latter can be set to the bypass shut-off position, in which case the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is shut off, water enters the tank and circulates in a small circle. The third position allows you to recharge the supply from the return system without blocking the full cycle of water passage throughout the entire circuit.
Conclusion
Specialists in Lately It is increasingly recommended to purchase Esbe brand products. The three-way valve, the instructions, the electrical diagram of which are 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, but it is important to choose the right model and install it in accordance with the technology.
A three-way valve in a water supply or heating system is responsible for mixing or separating liquids different temperatures, and also for obtaining the required temperature at the liquid outlet (adjusting the temperature of the coolant using a servo drive).
Design Features
The device body contains two inlets and one outlet for the flow of liquids and a control element, which can be different designs(for example, a rotary ball or a running rod), also a place for a servo drive.
Typically, the valve is not designed to completely shut off the output liquid flow, but is only capable of controlling the mixing proportions of liquids and the temperature in the system. The instructions do not suggest, but functionally, it is quite possible to shut off the liquid supply.
A three-way valve of a certain type, which performs separation functions, may have a rotary servo drive to redirect the flow to different pipes(then it is called “constipated”).
In this case, gradual or smooth mixing of liquids with temperature control does not occur, and the swivel mechanism consists of a ball (like ball valve Bugatti).
There are several varieties of it, depending on the type of drive mechanism, performing the same functions:
- Hydraulic rotary drive;
- Pneumatic drive;
- Electric servo drive.
Yes, three A new Esbe valve with a servo drive will require the sample itself and a compatible drive manufactured by the same company.
Types and differences
Esbe has been in business for over a hundred years and specializes in temperature control products for hydraulic systems in small buildings.
It produces a valve and rotary servo actuator for cooling or heating systems, also working in conjunction with indoor and outdoor temperature sensors in the system. The operating principle 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 (model series: 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 used for hot/cold water supply systems. This model range, like subsequent ones, has various options(for example, a 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 from brass alloys, designed to minimize leakage and with manual adjustment dial. The instructions indicate that they are also compatible with systems automatic control and Esbe controllers that allow you to automate the operation of valves.
Esbe three-way valve of this model series - supplied with standard sizes DN 15-50, pressure class - PN 10, model options include varieties with internal (three-way mixing valve type Esbe model VRG131 with connection to an actuator), external thread
(model VRG132), with union nut or compression fittings.
Trekhodo howl mixing Esbe crane The VRG330 series has similar qualities to the previously described VRG131 series (DN 20-50, PN 10), but is designed specifically to work with large flows (kvs difference between inputs is 60 percent).
Can also be equipped with compatible controllers and automatic control. Available with three connection types: internal thread, external thread, rotating nut.
According to Esbe specifications, the 3F series rotary mixing valves are designed for use in heating and cooling systems.
Esbe controllers and automatic control systems can also be used with them ( three way valve Esbe model VRG131 with electric drive is not immediately supplied, which allows you to choose the most convenient option company products).
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 PN 6 flanged pipe, model sizes are DN25-150.
The mixing valve from Esbe series H (DN25-40) and HG (DN25) is designed for installation in limited space.
This three-way control valve from Esbe is used only for heating systems and is specified for work with the boiler group (made of cast iron, special “H”-shaped body). It also has a reasonable price.
As the main type of connection, both internal thread and its mixed type are used. Compatible with Esbe controllers and drives like VRG131.
Models of the VRH130 series are also made in an “H”-shaped version, but made of brass with a pressure class of PN 10. This model is more versatile than the previous model and can also be used in water supply systems, and is available in different body widths.
Linear valves
The VLF300 series is a three-way linear mixing unit with standard sizes DN 15-50.
This model range is linen made of nodular cast iron and can be used with working fluid how cold/ hot water, and which contains non-freezing components (glycol, for example).
In the latter case, the sample must be equipped with a rod heater. It is equipped with a flange for a PN 6 pipe. Models similar to those previously indicated, VLF200 dn25, are distinguished by a higher operating pressure of up to 16 bar (versus 6 bar for the previously indicated model range).
Models VLE132 – made of bronze with standard 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 - PN16 external thread), unlike the VRG131 series. Its price ranges from 140 to 350 euros.
All linear three-way valves listed are compatible with the Esbe controller and actuator.
Thermostatic mixing valve
VTS520/550 - the instructions indicate that three-way valves are designed to work with hot water supply systems that are connected to the system solar heating. Its price starts from 150 euros.
A special 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 "anti-scald" features a sensor that automatically switches 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 - Esbe thermostatic mixing valve of this series is designed for use in domestic hot water systems, as well as in taps or showers where no other means of temperature control is provided (VTA330), or in high-flow domestic hot water systems (VTA530). Its price is around 150 euros.
Also equipped with a protection system you from burns. Pressure class PN 10 (material – brass, resistant to corrosion), available with external threaded connection, fittings or adapters.
VTA360/560 is a series similar to the previous one in design, but equipped with a large number of fittings and connections. The instructions assume that the drive of the Esbe three-way device of this series must also be compatible with the specifications specified by the company.
Representatives of the VTA320/520 series can be used both in conditions similar to the operating modes of previous model series, and in systems where other temperature control systems are present.
These valves are recommended for use in hot water circulation (HWC) or underfloor heating systems. Also equipped with “scald protection”. VTA370/570 – models designed for use in a “warm floor” system, have a high throughput.
VTA310 is a sample supplied with an adjustment knob, without a burn protection system. It is used in domestic water supply systems, including closed-circuit hot water supply (HWC) systems. Its price starts from 50 euros.

Installation features and prices
When installing a three-way mixing valve, choose various options, instructions and algorithms for installation. As a rule, the part is not installed directly to the heat source, since the system uses a gravity manifold or “hydraulic arrow”.
In the version for heating, the simplified instructions involve supplying coolant from the boiler to the valve, from there the coolant is supplied to the heating system through a pump.
The liquid that has passed through the heating system and cooled is sent to the boiler for heating, but also to the mixing valve, which ensures temperature control of the supplied substance.
The instructions for the Esbe three-way valve usually include a description of connecting the valve to the system, which may vary depending on the model range.
A three-way valve cw602n Esbe (the brand of brass is indicated here) of the VRG130 model series (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 drive).
The Esbe 3-way thermostatic valve (VTA 320) can cost $70 or more.

Flanged mixing valves Esbe 3F, 4FMixing flange valves ESBE 3F, 4F are made of cast iron and are widely used in heating and cooling systems. Esbe 3F valves can be used in closed systems with water that does not contain dissolved oxygen. When the Esbe 3F, 4F valve operates, the hotter coolant is mixed with the cold one entering the boiler, which ensures an increase in the temperature of the coolant returning to the boiler. This reduces the risk of low-temperature corrosion. The valves are manufactured in sizes DN 32-150. Flange connections, cast iron body, brass spool, EPDM seal, T=-10C...110C. Pmax=6 bar |

Three way mixing valve has a fairly simple device. It consists of a body with two inputs and one output, as well as a specially shaped rod on which a handle (for manual control) or an electric drive (for automatic control of the flow temperature) is installed. The rod is capable of rotating along a vertical axis, blocking to one degree or another the inlet of hot or cold water, due to which a certain flow ratio is created and, as a result, a mixture of a given temperature is obtained at the output. The body material of a three-way valve is most often brass alloy or cast iron. The rod is made of brass, cast iron or stainless steel.
Three way valve control is carried out using an electric drive mounted on the rod, which is supplied separately. The main characteristics of electric drives are: time of rotation of the rod by 90 degrees; the force with which the drive is capable of rotating the rod; electrical voltage and control signal (two-point, three-point, proportional). The electric drive receives a signal from the general building controller, which, based on the readings of various temperature sensors, calculates the position of the three-way valve stem to obtain the specified outlet temperature of the coolant.
Selecting an electric drive for a rotary three-way mixing valve. For coupling mixing valves ESBE actuators of the ARA600 series are used, for flanged cast iron valves - ESBE 90 series. If the valve is to be used as a diverter, the actuator must be with 2-position control. If used as a mixer, then 3-point control or proportional control is required: 0-10V signal. Next, select the desired combination of stem rotation time and valve purpose. For domestic hot water supply, 60 seconds will be enough, and to supply coolant to radiators, electric drives with a rod rotation time of 120 seconds are most often used. Monitor if necessary 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 specifications electric drives are determined, it will not be difficult to choose from the presented models exactly the one that will perform all the specified functions.
Esbe products are quite popular today. is no exception. It is one of many elements that are included in residential buildings.
Need for use
This design, on the one hand, is quite simple, but on the other, 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 all kinds of manufacturers. However, valves produced by Esbe have excellent performance characteristics. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.
Design features
Today you can find a wide range of Esbe products. The three-way valve is no exception. This element has a regulating component, which is a ball or 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 control element do not allow the flow of liquid to be blocked, distribution and mixing occurs. The most common and simple models are cranes.
Main advantage
Their main advantage is low cost and simplicity. However, if you need to adjust the Esbe three-way valve, then you should avoid purchasing simple devices, since they have the main disadvantage of not being able to stabilize the outlet temperature.
Carrying out installation work
Almost all of the described valves that are on the market are connected based on the same circuit. Mixing taps are most often used in water supply systems. Their main goal is to reduce the risk of backflow. There will inevitably be a pressure difference between the cold and hot water flows. It may cause backflow. If you install a valve, 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 like a warm floor.
Connection in the mixing unit
If you are interested in Esbe products, you can purchase a three-way valve at any relevant store. One has only to first consider how the faucet is used in a heated floor system. The application allows you to create an additional circuit in the system. It is connected to two points, which allows for constant circulation of water at the outlet. As for the input, the flow is provided only if there is a need to obtain additional heat. A valve with a thermostat is connected to the mixing unit. Due to the fact that all the valves are located at the point, they are narrowed, which can cause insufficient flow 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 bore. The Esbe three-way valve, the connection diagram of which can be developed based on the instructions presented in the article, may suggest insufficient flow power 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 resolved in two ways: the first involves narrowing the second line, while the other option is to install it on it. The latter option is considered more productive, as it allows you to adjust the flow.
Alternative option for installation work
The Esbe three-way valve can be installed using another method. It does not involve the use of a balancing valve. The pump is connected to the second line, ultimately the temperature of the output and input streams is equalized. The faucet with thermostat is located in systems with one circuit. The simplest example of such systems is heated floors in small rooms. In this case, it is not always justified to create a mixing unit with large dimensions. It would be 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 flows. In this case, the thermostat will cause the shut-off valves to move, the cross-section will be increased, and the flow will be open. As soon as the pipe is heated, the temperature 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 installation is to prevent the flow of cold water from entering the incoming pipeline, which is connected to the heating equipment. If this requirement is not taken into account, condensation will form on the pipes, and temperature changes will lead to deformation at the joint points. If we talk about the consequences of deformation, then in the best case you will encounter a small leak, while in the worst case the system will need to be completely changed. In order to avoid the need for repair of 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, you can ensure that water with a temperature below 50 degrees does not enter the equipment inlet. Temperature differences are significantly reduced, and the negative effects of cold are reduced. Experts advise supplementing systems that use plastic pipelines with mixing valves. In this case, the task is to prevent high-temperature water from entering the pipeline. Despite the fact that polymers have many advantages, they do not cope well with frequent temperature changes that may be higher than operating temperatures.
When exposed to such conditions, the pipeline system soon fails. 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, you will be able to provide temperature readings ranging from 75 to 85 degrees, which are recommended by experts. Installing a valve can solve many problems, but 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, installation and adjustment instructions for which are presented in the article - you must remember that with the help of this device it is possible to mix cooled water from the return to 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 placed directly in front of the heated floor circuit. The handle allows you to open the bypass, while circulation pumps and the equipment draws in cooled coolant from the return line, where it mixes with hot water. In order for the adjustment to be made as efficiently as possible, you need to understand what happens at certain positions of the handle. The latter can be set to the bypass shut-off position, in which case the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is shut off, water enters the tank and circulates in a small circle. The third position allows you to recharge the supply from the return system without blocking the full cycle of water passage throughout the entire circuit.
Conclusion
Experts have recently increasingly recommended purchasing Esbe brand products. The three-way valve, the instructions, the electrical diagram of which are 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, but it is important to choose the right model and install it in accordance with the technology.
I provide passport data and a video of the servo drive working. I also show how to connect and mount and then configure the servomotor for a three-way valve.
And so let's get started...
In this article we will look at the most versatile servo drive today, ESBE 99K2, which is shown in the picture, and the ESBE VRG131 valve.
The servomotor is sold with two connection kits, for two different standards of three-way valves with a circular rotating valve for unlimited rotation. More details will be indicated both in the passport and in the video.
It's important to understand:
1. The three-way valve itself contains a ball valve that rotates in a circular manner for unlimited rotation. For work, the valve must be turned clockwise and counterclockwise from 90-180 degrees of rotation.
2. Servo drive is electrical equipment and a device for rotating this ball valve. By rotating the valve, two passages are opened and closed, and the third passage is constantly open. The servo drive, through a temperature sensor, rotates in the desired direction to open or close the feed hotline circulation. More details in the video and in the passport. We also look at how to configure the valve for a specific circuit.
Servo drive ESBE 99K2, advantages:
- Power supply 220 Volt
- Electrical remote temperature sensor
- Temperature adjustment(15-70 degrees) in real time
- Adjusting the time (1-70 seconds) for checking the temperature sensor and turning on the rotation.
- Rotation adjustment: from 10-180 degrees
- Switching rotation clockwise and counterclockwise (reverse)
At 90 degrees, it is possible to set the required rotation of the ball valve in real time for testing (press the button and scroll). If a 180 degree rotation is required, the handle is not installed and adjustment cannot be made. And this is of no use, the function is only useful for masters when testing the mixing unit.
Flaw: If there is no power, the valve does not return to any position, but freezes in the position in which it was set automatically.
But in general it is used for large objects where it is necessary to make mixing unit with high flow rate (from 2 cubic meters per hour and above).

Esbe valves - technical features of devices
Esbe valves are types of devices used to regulate liquid or gas when it is supplied from one pipe to another. The three-way valve type is distinguished by the presence of three connections, which allow you to effectively redirect flows in the system, especially in the case of mixing hot and cold water.
Adjusting the operation of valves of this type within one system can carry out servo drive. This device needs to be given 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 to purchase and easy to install, which is why it is most often used for.
Depending on 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 Electrical adjustment is not used. In such cases, special devices are used to regulate the operation of equipment.
These varieties include, for example, the dn25 valve, which can be mounted in a faucet without a drive.

Purpose of Esbe valves
This type of product can be used in a wide range of systems, including heating systems, even centralized, hot and 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. You can 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 select a product for any tap. It is only important to choose the right type of product and install it according to the recommendations. It is also very important to adjust the servo drive or thermostatic regulator for the system to operate properly.
Then the model you choose will work without failures, regardless of the specified technical parameters.
The advantages of using this particular type of valve
Among the main advantages of installing Esbe products are:
- Easy to install this type of component, the ability to install samples in virtually any system.
- Wide operating temperature range, especially for models such as the vrg131 rotary valve.
- Versatility in application - can be used in networks with different loads.
- There is no need to maintain such samples when correct installation similar equipment.
- Can be used with any Esbe drive that has the required technical characteristics.
- The presence in some parts of the so-called Anti-scald functions– automatic shutdown of hot water supply if cold water stops flowing into the system.
Popular Esbe valve models
Currently, the following Esbe valve models are particularly popular on sale:
- VTA200 equipment is the best tap for all water supply systems. Applicable for systems without hot water recirculation, as well as HWCs with such a function. Do not require special maintenance;
- VTA270 is a model range suitable for installation in underfloor heating systems. They can be installed in systems where there is no risk of “burning”. Suitable for systems with a fairly large area - up to 100 square meters;
- VTA310 is a piece of equipment, like the vrg131 rotary valve, suitable for all water supply systems that do not have special requirements for protection against burns. Designed for areas with a maximum coolant temperature of 95 degrees, withstand differential pressure of 0.3 MPa. This type of valve can be mounted in a faucet with any type of drive;
- VTA330/VTA360 is equipment that is installed in systems that do not have additional devices for temperature control. The peculiarities of this equipment are that it, like the 3-way faucet vrg131, reacts as sensitively as possible to changes in pressure in the system and allows you to maintain a stable water temperature even during pressure surges. This model comes with a special protective cover, unless, of course, the user has chosen a different package. Parts VTA330/VTA360 are distinguishable only by the direction of water flow;
- VTC300 – thermostatic mixer. The crane is used for installation with boilers with a power of up to 30 kW. It is used in cases where coolant at a sufficiently low temperature flows 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 the system you choose;
- DN25 is another particularly popular valve model. Represents . Also suitable for protecting boilers power up to 150 kW. The operating temperature of this sample is also 110 degrees. DN25 is completely unpretentious to installation conditions, its operating efficiency does not depend on the chosen installation position;
- model vrg131 - designed directly for use in hot water supply networks. The vrg is made from a specialized brass alloy, which significantly increases its service life. Can be installed manually. It is recommended to use a servo drive from the same manufacturer to control this three-way valve.
