Three-way mixing valves (taps, valves) and actuators ESBE

Esbe three-way valves are usually used as mixing valves, but can be used as switching or separating valves. It is necessary to ensure that the pressure rating, pressure drop and leakage are within acceptable limits. This information given for each valve.
Four-way valves are usually used when a high return coolant temperature is required (usually for solid fuel boilers). In systems with two heat sources or a storage tank, valves will help prioritize the use of an inexpensive heat source while maintaining good temperature separation in the storage tank.
Operating principle of Esbe 3-way valves VRG130. The required temperature in the system is achieved by adding required quantities water coming from the return pipe supplied to the boiler.

How does Esbe three way valve work?

The required temperature in the heating system is ensured by proportionally adding colder coolant to the hotter coolant flow from the boiler.

How does a four way valve work?

Valves of this type have a double mixing function, that is, the hotter coolant is mixed with the colder coolant supplied to the boiler. This allows you to increase the temperature of the coolant in the return (returning to the boiler) and reduce the risk of low-temperature corrosion, which significantly extends the operating time of the boiler.

Operating principle of Esbe 3, 4, 5 way and bivalent mixing valves

Advantages of Esbe mixing valves:

• Easy to install drives.
• Compact size, lightness and ease of installation - installation requires a minimum of tools.
• Minimum dimensions of mixing valves, facilitating installation in cramped conditions.
• Reliable valve installation with internal thread. The key edges are wider and have two edges instead of six. This provides a better grip and less risk of the pipe wrench or box wrench slipping.
• More flexible cable connection. The drives are supplied complete with a connecting cable and an additional cable contact. The advantage is that you can run a separate cable, for example, directly to the circulation pump without connecting through a central controller.
• High control accuracy.
• Minimum delay and high accuracy of the entire cycle, from complete closure Until the valve is fully opened, the valves provide the ability to use the full angle of rotation. This adjustment is as close to ideal as possible and provides increased comfort and reduced energy consumption.
• Esbe valves are renowned for their minimal internal leakage and have been awarded the " Best product plumbing equipment 2003".
• The leakage rate is reduced from 0.1 to 0.05%. And this is achieved at double pressure, i.e. at 100 kPa (1.0 bar). A valve that provides tighter closure is difficult to find and buy on the rotary valve market.
• Easy and convenient regulation, high performance
• Reliable and have a long service life

What is Kvs? Each mixing valve has a Kvs characteristic ( throughput m3/h at a pressure loss of 1 bar). The Kvs parameter helps determine which valve is needed for your heating system. You can determine the Kvs of the Esbe valve using the graph below.

Esbe mixing valve size selection

Selection of Esbe mixing valves of the VRG and VRB series for floor or radiator system heating.
We start from the thermal power of the boiler in kW (for example, 25 kW). We move vertically to the selected temperature mode t (for example, 15°C). Next, we move horizontally to the shaded area (pressure drop range 3-15 kPa) and select a lower value of the Kvs coefficient (for example, 4.0).
In this case we select desired type valve with coefficient Kvs=4.0

The Kvs value is taken for flow in one direction only
Valid for 4-way valves double meaning pressure drop P indicated on the graph.

Materials used, coolant requirements.

The VRG, VRB and 5MG series valves are manufactured from a special brass alloy (DZR Dezincification Resistant Brass, CW 602N), offering advantages that cannot be achieved in designs combining cast iron and brass. This allows them to be used for water supply systems with sanitary hot water.
Selective corrosion of brass(ordinary brass releases zinc, leaving a brittle, porous copper mass) is the most dangerous type of corrosion, leading to a rapid decrease in service life and loss of functionality. Coating the inner surface of valves and valves with a layer DZR reduces the likelihood of contaminants and sediment sticking to the valves, which ensures reduced wear and more clean water. The alloy also contains less lead than many other products. and is especially suitable for the installation of cold water supply systems.
All other ESBE valves can only be used in closed systems with water that does not contain dissolved oxygen.
To protect against freezing, it is allowed to use a coolant containing glycol and additives that neutralize dissolved oxygen, with a concentration of up to a maximum of 50%. When glycol is added to water, its viscosity increases and its heat capacity changes, so this must be taken into account when choosing a valve. If the percentage of glycol is 30-50%, then in this case it is necessary to select another valve with a higher Kv coefficient by one level. Lower glycol content does not affect the valve's operation.

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

general information

A three-way valve is a device for regulating pipeline networks with liquid working environment. To explain it in a popular way, 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 fluid.
3. Dynamic redirection makes it possible to obtain a stream of stable temperature.

Design features of the three-way valve ESBE

Adjustment three way valve carried out using a rod 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 the flow is completely blocked working fluid does not happen: it is only mixed and redirected. The simplest example of such a device is a regular faucet. His strong point – simple design and low cost; weak – impossibility of obtaining a stable outlet temperature. Despite all their shortcomings, taps are widely used in underfloor heating systems.

If you introduce into the design of a conventional crane electric drive, then it will be possible to significantly increase its functionality: the device will be able to regulate the temperature of the liquid medium automatically. The task of simple balancing valves is to adjust the cross-section to the flow of the working flow.

The device works something like this:

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

For commercially available models, the knob turns may differ slightly, which does not in any way affect the principle of operation of the devices.

Main varieties

Three-way valves come in three types:

• Hydraulic.
• Electrically driven.
• Pneumatic.

Electrically driven appliances (for example, model ESBE) are slightly different in their operating principle. The electrical appendage acts here like a regular thermostat: thanks to it, the flows are not only mixed, but also maintained 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. At the same time, the cross-section at the inlet of the cold flow changes, which makes it possible to impart a stable temperature to the outlet water. In this case, the three-way valve is completely dispensed with without human control: the control of the equipment falls on automation.

The ESBE valve with electric drive 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 necessary to mix two liquid streams and maintain a stable temperature. Even the highest quality and reliable models of a three-way valve with a thermostat have one common drawback for products of this type: the inlet points through which liquid flows are greatly narrowed. As a consequence, this provokes an increase in hydraulic resistance.

These types of taps are great for water pipes. ESBE valves are often equipped with heated floors, although a special connection diagram is used. 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. Thermostatic varieties use thermostats with a remote-type sensor. In addition, the operating principle here is also different.

Unlike standard models, thermostatic valves control flow at only one point. The other two inlets are in a permanently open position, with a stable cross-section. When purchasing such a design, it is important to test the second point for narrowness, otherwise difficulties in the operation of the device may arise due to high hydraulic resistance. If such a defect is detected, 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, you can consider installing an esbe three-way valve. It's better to start with plumbing system, Where mixing taps occur most often. The valves in this case prevent the formation of reverse flow. The fact is that cold and hot flows have different pressures, which provokes differences. This may result in backflow. Systems with ESBE valves are completely safe in this regard.

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

• Mixers for the "warm floor" system.
• Pipe entering the boiler. In this way, 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 heated floors has its own specifics. Location mixing unit is an additional circuit. Switching with the manifold-distributor is carried out through two points: this allows the coolant at the inlet to constantly circulate. The inlet flow is opened only when there is a need for additional heat.

The mixing unit is connected to the valve and thermostat. You need to understand that a thermostat for a water heated floor allows you to reduce heating costs. Considering the narrowness of all valves at point 2, the pump may encounter problems with insufficient flow. To solve the problem, it is necessary to install a second line that 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 power, 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 will narrow.
2. A balancing valve is installed.

The second method is considered more effective, because In this case, the flow is adjusted more accurately. There is another scheme for connecting an esbe three-way valve for a heated floor - connecting the pump to the second line: here a balancing valve is not needed. This allows you to level temperature regime in the input and output stream.

Installation of a faucet 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, using a large mixing unit is not very practical. A more expedient solution would be to connect a single-circuit heated floor. The installation of a three-way valve with a thermostat is carried out on the return pipe containing the cooled coolant. Thanks to the thermostat, shut-off valves are 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 entering the pipeline entering the boiler. If this is not done, the pipes will begin to become covered with condensation, and a dangerous temperature difference will arise in the system. This is fraught with deformation of the connecting areas, the most harmless consequence of which will be the appearance of small leaks. If you do not react in time, the system may completely fail.

Particular responsibility should be taken when installing shut-off valves in the piping solid fuel boiler, during the operation of which significant temperature changes occur (read also: " "). The mixing valve allows you to protect the boiler equipment from the ingress of coolant with a temperature below +50 degrees. This reduces the temperature difference, which has a beneficial effect on the efficiency and durability of the system.

Experts recommend using mixing valves also in systems with plastic pipelines. Although polymer communications have a number of advantages, frequent excesses of operating temperature parameters have a destructive effect on them. According to standards, the most comfortable temperature range 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 utility network.

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 exclude the purchase simple devices, since they have a main disadvantage, expressed in the inability to stabilize the temperature regime at the outlet.

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. Between the flows of cold and hot water A pressure drop will inevitably occur. 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 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 mount it on it. The latter option is considered more productive, as it allows you to adjust the flow.

An 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 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 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 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, 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

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.

The ESBE type 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 presented by different manufacturers. Three-way valves produced under the ESBE brand have good performance characteristics.

Some useful knowledge

Three way rotary valve ESBE

A three-way valve is a control device in pipeline systems with a liquid working medium. Speaking in simple language, built into the design of the heating network, it will act like a well-known faucet 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 required temperature of the working fluid by mixing hot and cold flow.
• Receiving a jet with constant temperature through dynamic redirection.

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

Design

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

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

Modifications on the market may have different handle rotations, but the principle of their operation remains the same. The tap and its position are manually adjusted, thereby ensuring a balance between the two flows.

Kinds

There are several types of such devices:

• With hydraulic drive.
• With pneumatic drive.
• Electrically driven.

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 allows you not only to mix flows, but to maintain set temperature. When the temperature decreases/increases, 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 point of inlet of the cold flow also changes. The result is water with a constant temperature. No human intervention crane ESBE does not require. Its operation is regulated automatically.

Valve operating principle

Equipped with electric actuators and thermostats, ESBE valves are equally suitable 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 liquid streams with constant temperature maintenance. 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.

This disadvantage is the strong narrowing of the entrance points. The narrowed cross-section of the inlet point, in turn, increases hydraulic resistance.

Such a faucet will work well in water supply systems. ESBE valves are suitable for installation in underfloor heating systems, but require a special connection diagram. In addition to the designs described above, three-way thermostatic valves are available on the market. These devices are often confused with each other, but they are still 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 at only one point, the remaining two are open and their cross-section does not change. When choosing such a design, you need to check whether there is any narrowing at point 2, otherwise 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.

Connection diagrams

Three-way valve - connection diagram

Almost all three-way valves on the market are connected according to the same circuit. Let's look at it using ESBE cranes as an example. Let's start with water supply systems, since this is where the mixer tap is used most often. The main purpose for which the valve is installed is to reduce the risk of backflow.. Between the two streams - cold and hot water - there will inevitably be a pressure difference. It can lead to backflow. When installing ESBE valves, such incidents rarely occur. In heating systems, ESBE valves are used in only three directions:

• In mixing units of “warm floor” systems.
• To stabilize the temperature of the liquid flow in the incoming boiler pipeline.
• To reduce the supply of high-temperature coolant from the boiler to the pipeline.

Valve in the mixing unit

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

Diagram of a heated floor with a three-way valve

If there is insufficient flow power on the first line, the thermostat will not be able to open the passage to the required amount . The problem is easily solved in two ways: by narrowing the second line or installing it on balancing valve. The second method 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 pump equipment connects to the second line. As a result, the temperature of the inlet and outlet streams is compared. A faucet with a thermostat can be installed in systems with one circuit. The simplest example of such systems is heated floors in small spaces. Creating a mixing unit here , with its considerable dimensions , is not always justified. It is better to connect a heated floor with one circuit. A three-way valve with a thermostat is installed on the return line, through which the 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 cold coolant flow into 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 will form, at worst, the system will have to be completely changed.

Three-way valve in a heating system

It is especially important to connect shut-off valves to solid fuel boilers, characterized by significant temperature changes during operation. Connecting a mixing valve makes it possible to ensure that liquid with a temperature below 50 degrees does not enter the inlet of the boiler equipment. 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. The goal here is to prevent coolant from entering the pipeline high temperature. Despite all the advantages of polymers, they do not withstand frequent increases in temperatures above operating parameters. Under such operating conditions, the pipeline quickly collapses. Temperatures recommended by experts range from 75 to 85 degrees. Installing valves can solve many problems, but the model must be selected exactly according to technical characteristics utility network, and must have sufficient passage.

Conclusion

The simplest shut-off valves - three-way mixing valves - important element engineering communications. Modern models created at the intersection of old traditions and modern technologies, allowed us to achieve excellent results their use for a variety of purposes.

Esbe valves are one of the most reliable and functional components used in various systems ah water supply, including domestic and main. Has a very wide the lineup, 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 this correctly, let's understand the intricacies of working with such equipment and the features of its use.

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.

By 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. 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.

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:

1. Easy to install this type of component, the ability to install samples in virtually any system.
2. Wide operating temperature range, especially for models such as the vrg131 rotary valve.
3. Versatility in application - can be used in networks with different loads.
4. There is no need to maintain such samples when correct installation similar equipment.
5. Can be used with any Esbe drive that has the required technical characteristics.
6. 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 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.
