Balancing valve on the battery. Balancing valves: why they are needed and why they are effective

Any heating system needs timely and high-quality adjustment; these manipulations can be carried out in a variety of ways.

Only if all parameters in individual sections of the network are as close as possible to the calculated data will it be possible to achieve high operating efficiency.

That is why, for high-quality adjustment, a universal balancing valve for the heating system.

Requires precise superstructure of all data for maximum efficient work

a brief description of

Every heating system needs professional hydraulic tuning. The main task of such adjustment is to regulate fuel consumption to the initial calculated indicator, so that to each installed battery the required amount of heat was supplied. The system setup itself displays the final water consumption for a certain area, which was previously calculated.

It must be remembered that any water system requires initial setup

Traditional schemes involve ensuring optimal flow rates with a special pipe diameter. If the heating system has more complex configurations, then adjustment is carried out with universal washers.

Each of them has a certain passage diameter, due to which the required volume of water is supplied.

Of course, such configuration methods do not apply to innovative technologies, since in modern world It is common to use an automatic balancing valve for a heating system. It is customary to add two fittings to this mechanism, which constantly test the pressure value in different zones in relation to the main control device.

Such parts are also used for mounting a specific capillary tube. Experts say that modern fittings interact perfectly with various controls.

In this video you will learn how the balancing valve works:

Features and Benefits

Those who have already worked with control valves note that their characteristics are almost similar to other pipeline elements. For the manufacture of such parts, brass and bronze are used, but galvanized products can also be found. Interesting fact It is believed that more than 90% of the total assortment on the world market is occupied by brass valves. This trend arose due to their reliability and durability.

Reliability and durability are the main factors when choosing a valve

Among the many positive characteristics Balancing valves for heating systems include the following:

1. Affordable price.
2. The work associated with the planned setup of the system is significantly simplified.
3. High degree of reliability.
4. The master has an excellent opportunity to fine-tune the temperature and pressure level.
5. Long service life.

There are practically no negative characteristics of such products. In addition, in domestic use there is simply no alternative to balancing valves.

Types of valves and their design features

Today there are two types of control valves, each of which has its own performance characteristics. Before buying a particular model, you need to carefully study their basic description. Most often, all specialists install the following balancing valves:

1. Universal unit with automatic system management. A special feature of such products is that they completely control the heating system without human intervention. The functionality of the valve allows you to maintain a constant pressure difference between the return and supply two-pipe system. Concerning single-pipe heating, the device controls the continuous flow of coolant. Available for sale multifunctional models, which work perfectly in tandem with each other. The use of such units leads to changes in the flow rate and pressure difference in the pipeline. It is worth noting that the coordinated operation of such valves occurs thanks to a special impulse tube. Interior The automatic device is more reminiscent of a piston pressure reducer. But they should not be confused, because they perform completely different functions.
2. Manual valve. This device occupies a leading position in demand due to affordable price and durability.

Any quality part should include o-rings, for example

But among the main ones design features experts note several nuances. The thing is that a high-quality part must consist of the following elements:

1. Universal adjustment spindle. home working part presented in the form of a cone screwed into a special saddle. At the moment the spindle is activated, the coolant flow is completely blocked.
2. The cap, which can be made from various materials, but most often made of plastic. It is worth noting that metal products are considered to be of the highest quality and most durable.
3. A durable brass body, which is equipped with all the necessary threaded pipes so that the user can connect the pipes. In the internal compartment of the device there is a special seat in the form of a small vertical channel.
4. O-rings made of high quality rubber.

But main feature Such a valve is that it is equipped with two fittings at once.

These units perform the following functions:

1. They control the pressure level inside the system both before and after the valve.
2. Provide reliable fixation of the capillary tube.

Each fitting necessarily measures the pressure level, and if during operation sudden changes in values ​​were detected on the regulating mechanism, then the water flow is calculated.

Three-way valve for heating systems:

Operating principle according to the standard scheme

Novice craftsmen are often interested in why a balancing valve is needed in a heating system. But before you meet functionality this unit, it is necessary to study the principle of setting up the system. It is enough for the master to imagine a dead-end branch with several standard batteries, which act as a kind of source of energy consumption. A certain volume of heated coolant is supplied to them.

It is worth noting that the design temperature is selected based on the fact that it is enough to heat a certain room.

The exact cost figure will be known only after the master has carried out all the necessary calculations.

Difficulties arise when special thermostatic valves are not installed on the radiators. The thing is that any hydraulic adjustments will be made using a manual balancing valve. Fix this part on the return pipeline. When all necessary calculations produced, then the valve is set to a certain number of revolutions. As practice shows, in the regulated branch there is always constant flow.

During installation, you will save on radiators

Despite this, many owners of private houses are wondering how to properly adjust the valve when the flow changes periodically. Initially, it should be noted that this situation occurs when conventional radiators are equipped with universal thermostatic regulators responsible for heating the room. Such details can create an additional obstacle in the path of water, which will affect the flow intensity. In this case, the flow rates will change significantly in the return pipeline.

Timely installation of balancing devices will allow you to achieve the effect when you do not need to install too many radiators (usually 5 pieces are enough). If the master decides to limit the thermostat control limits, he will be able to quickly adjust the heating circuit.

Of course, there can be more than five radiators, but they will definitely go to waste. If you block the flow of coolant from the thermostat of the first radiator, the technician will be faced with an increase in flow to the second battery. The valve will definitely close, and the flow will go to the next unit. It is this principle of operation that will be considered relevant for all heat consumers. If the technician does not take urgent measures, then some radiators will overheat very much, while others, on the contrary, will not have enough coolant.

Balancing valve with internal thread STAD:

Professional installation

Installation and adjustment of the balancing valve is not considered difficult, since Every man can cope with these tasks. The main difficulty can only arise from the fact that it will be difficult for the master to achieve a certain position of the unit. The arrow on the body must be in the direction of water movement. Only in this case can you obtain the optimal design resistance and correct flow rate. Some modern manufacturers allow installation of the valve both in the direction and against the main flow. Depending on the chosen model, the rod may occupy different positions.

A quality valve must provide for the need reliable protection working parts of the valves: ingress of various mechanical contaminants is unacceptable. It is for this purpose that a special mud trap or filter is mounted in front of the device. To avoid turbulent water flow, it is necessary to provide straight sections of pipe of sufficient length both before and after the valve.

It is worth noting that this very requirement is included in the accompanying documentation of reliable manufacturers.

Network balancing

Most often, those masters who professional level engaged in the installation of heating systems, determine the coolant flow on the batteries very in a simple way : take the total number of revolutions of the balancing valve and divide by the number of heating devices used. These simple steps help you find out optimal step adjustments. Gradually moving from the last radiator to the first, carefully close the taps with the resulting difference in speed.

In addition to the main adjustment method, there is an additional, possibly more accurate

Of course, this method is approximate, since it does not provide for the option that batteries can be of different power. That is why it is better to use it for preliminary tuning, which allows for certain corrections to be made during active operation.

A completely different method, which is based on measuring the actual surface temperature of batteries, deserves special attention. The balancing valve can be adjusted correctly as follows:

1. Initially, you need to gradually open absolutely all the valves and put the system into operating mode with a supply temperature of +80˚C.
2. Using a contact thermometer, measure the temperature of each heating device.
3. All differences in data must be eliminated by tightening the taps of the middle and first batteries. It is forbidden to touch the latter. The near radiator should be opened slightly by 1.5 turns of the valve, but the middle ones by 2.5.
4. The system needs to be given a little time to adapt to completely new operating conditions. After 30 minutes, you need to take measurements again. The main task of the master is to achieve a minimum temperature difference between the batteries closest and farthest to the boiler.

It is also worth considering that weather conditions and the temperature outside the window do not affect the performance at all, only the difference in the heating of the radiators is important.

Disassembly of automatic balancing valves ASV series:

Experienced installers of heating systems note that any adjustment work should be carried out on the basis of calculated data, which is especially important when drawing up project documentation. To prevent errors, you need to use a special valve diagram and measurements taken in advance. The adjustment process begins only when the handle rotates and the spindle moves. If the master does not have all the necessary measurements at hand, then the adjustment process itself will be considered conditional. In this case, efficiency and accuracy cannot even be discussed.

As for straight pipe sections that prevent water turbulence, their length should be at least 10 cm. If we are talking about an automatic device, then the main unit must have a fitting that plays important role when filling the circuit with the inlet valve closed.

Whatever the heating system, it requires adjustment, which can be done in a certain way. This is necessary so that the parameters in individual areas are close to the calculated ones. This makes it possible to achieve operational efficiency. To adjust you can use different means, however, the most common and modern is the balancing valve, the operating principle of which is presented in the article.

Need for use

Heating systems require balancing, which is a hydraulic adjustment. The purpose of these manipulations is to bring the individual branches of the circuit to the required value; this is the only way that each radiator will receive required quantity heat. If we are talking about simple systems, the required coolant flow is ensured using correctly selected pipe diameters.

Use in complex systems

Complex systems require adjustment in their operation using special washers, the size of the passage of which ensures the flow of water into the required volume. Listed methods are obsolete, in use today modern way, which is expressed in the installation of balancing valves. These devices are manual valves that are used to regulate the flow of coolant. The mechanism has an addition that blocks the flow; fittings are used for this.

Principle of operation

Once you have learned what the operating principle of which will be described below is used for, you can begin installing the device. First, you need to understand the principle. To do this, you can imagine a dead-end branch that has several radiators, the latter acting as energy consumers. A certain volume of coolant, heated to the design temperature, is supplied to them through the pipes. It is determined depending on how much thermal energy will be needed to heat the premises.

It is used when there are no radiators and the water flow for each of them is constant. The mentioned device should be located on the return pipeline, in a place where it can be inserted into the common line. This allows you to carry out the necessary measurements by setting the valve to the required number of revolutions. A certain constant flow of water in the regulated branch will be guaranteed. However, users quite often encounter that the flow rate changes; this can happen when thermostatic regulators are installed on radiators. They are designed to control the intensity of heating of the room and create an obstacle in the way of water, reducing the volume of its flow. In this case, the flow rate of the coolant volume in the return common pipeline will change.

For reference

A manual balancing valve will guarantee a certain volume of coolant, which will allow you to achieve the desired effect when the number of batteries is small and does not reach 5 pieces. If you limit the control limits of thermostats, then the existing circuit can be easily customized. If the number of radiators is more than mentioned, then they will go to waste. The thermostat installed on the first battery will block the flow of coolant, which will cause an increase in flow on the second radiator. The valve on it will close, the flow will move to the third radiator, and so on. Ultimately, such work will lead to the fact that some batteries will overheat unnecessarily, while others will remain cold, and the branch will become unbalanced. An automatic balancing valve must be installed on a riser or branch with a sufficiently large number of heating devices, only then the system will work smoothly.

Operating principle of a valve on a riser with a large number of radiators

If an automatic balancing valve is used under the conditions described above, then the operating principle is somewhat different. The valve is adjusted to the maximum design water flow. During operation, when the thermostat of any battery will reduce consumption hot water, the pressure in the area will begin to increase. The automatic regulator will receive an impulse through a capillary tube, this will allow the device to quickly respond by adjusting the water flow, then the remaining thermostats will not have time to operate, the flow will not be blocked, and the system will remain hydraulically balanced.

Classification

The balancing valve, the operating principle of which was described above, is offered for sale in a wide range. Before you make a purchase, you must understand the classification. Thus, when choosing, it is necessary to take into account the design parameters of the system at the installation point. The master must pay attention to maximum pressure working environment and nominal parameter, and also take into account the pressure difference in the return and supply circuits.

The valve may belong to one or another class depending on the area of ​​use. Thus, the devices are used at facilities individual construction, housing and communal services, in industrial facilities and on sections of main pipelines. The balancing valve, the operating principle of which you should know before purchasing the device, can be selected according to the type of piping system, which is designed for air conditioning, hot or cold water supply, cooling or heating. Among other things, the devices described differ in the type of coolant, such as steam, water or glycol solution. According to the type of installation, valves are divided into fixed and adjustable.

Main types of valves

If you are interested in the MSV balancing valve, then it is offered for sale in a wide variety; among other models, you can see devices with manual adjustment, with the help of which it is easy to adjust individual sections of the system and the entire pipeline, determining the pressure and flow of the medium at control points. Using manual balancing valves, you can turn off individual areas, freeing them from the working coolant. The main advantage is low cost, but you should pay attention to some disadvantages. Among the main ones is the ability to set balance only for average calculated parameters direct current. When the flow fluctuates, what happens in water supply systems, the balancing may be disrupted.

An automatic balancing valve, the price of which is 6,000 rubles, can be automatic; it is installed on the return and inlet circuits. Another type of valve provides the ability to regulate the temperature of the working environment.

Installation Features

If you decide to purchase a Danfoss balancing valve, you should first familiarize yourself with the installation features. In order to guarantee the accuracy of measurements, there must be sections of pipe without bends before and after the device. The length of the section will depend on the diameter. Before the valve, the length of the straight pipe should be equal to 5 pipe diameters, after the valve the length should be two diameters or more. If these recommendations are not taken into account when installing a Danfoss balancing valve, the error in measurements can reach 20%.

The operation of a heating system is often accompanied by uneven distribution of coolant throughout the circuit and connected devices. This can lead to pressure and temperature changes that negatively affect heating efficiency and can damage equipment. A balancing valve helps prevent these consequences, various models which are sold by Forsterm.

Manual balancing valve: operating principle and purpose

This device is a type of pipeline fittings and is used for the calculated distribution of coolant along the circuit and equalization of its pressure and temperature. Regardless of what design the balancing valve has, its operating principle is based on changing the throughput of the pipeline by increasing or decreasing the flow area. This is achieved by gradually moving the spool relative to the inlet of the device, and therefore the device allows for smooth adjustment.

Videos, diagrams of balancing systems

By using a flow meter, flow balancing operations are simplified since the flow value can be read and adjusted at any time without resorting to differential pressure gauges and reference graphs.

Video: circuit balancing devices

The differential pressure regulator maintains constant, at a set value, the pressure difference existing between two points in the hydraulic circuit.

Video: balancing valve - operating principle and diagram (flow stabilizer)

AUTOFLOW devices are capable of automatically balancing the hydraulic circuit, ensuring the design flow at each terminal. Even if the circuit is partially closed due to control valves, the flow rates in the open circuits remain constant at nominal values. The system always provides the best comfort and provides the greatest energy savings.

Range of balancing valves for heating systems

In the catalog you can choose pipeline fittings the following types:

• manual balancing valve - such a device is regulated using a valve and is used in systems with constant pressure levels, for example home heating and water supply;
• automatic balancing valve - such valves are equipped with electric or electrothermal actuators and are suitable for installation in systems with dynamically changing pressure that require fast and accurate response.

The catalog also presents various components that optimize and expand the functionality of valves, in particular flow stabilizers and actuators.

The functionality of existing devices can significantly increase the efficiency of heating or water supply. Their use will extend the operational life of the equipment, reduce noise in the water supply and the likelihood of pressure surges. In our catalog you can find detailed information technical description, which accompanies each balancing valve for the heating system, and Forsterm employees will provide detailed instructions on the selection, installation and operation of this valve.

Everyone wants to have an economical and, at the same time, ideal heating system in their home. Unfortunately, this doesn’t always happen in life.

It is enough for designers to make a mistake in hydraulic or thermal calculations, and additional expenses for the heating system are provided.

Incorrectly selected heating fittings will also contribute. In order for the heating system to perform its functions reliably and correctly, heating engineers have in their arsenal various ways achieving this goal.

The need for balancing

The design of a heating system assumes that at each heating point the heating device will produce the required amount of heat. Unfortunately, in practice this does not always look like this.

This picture is especially noticeable in multi-storey buildings. It is not uncommon to see a picture where the lower floors are literally suffocating from the heat, while at the same time the radiators on the upper floors are lukewarm.

The same situation arises with the heating of entrances. It is much warmer in the one located closer to the DHW inlet into the house.

This difference in temperature difference is explained by the fact that the closer the heating radiator is to the hot water input, the more heat he gets. Naturally, he gives. Remote heating devices receive less heat, so they are cooler. This means that the hydraulic adjustment of the system is broken. The balance of heat distribution has disappeared.

There are few reasons for system imbalance. The main ones are:

• errors in system installation;
• error in the project or its change;
• airing of the system;
• mismanagement of the heating system;
• ignoring seasonal maintenance.

It becomes necessary to adjust it to restore uniform heating. As a result of this work, each heating device will receive the calculated amount of heat. Temperature will level out, the whole house will be equally warm. To achieve this goal, balancing valves are used.

It is worth noting: Installing a balancing system will ensure uniform heating of each heating device in the house.

Types of cranes

Balancing valves are divided into automatic and manual.

Manual ones are designed to configure the network during its installation, and automatic ones change the parameters of the heating network during its operation.

When selecting a valve, it is necessary to take into account many parameters, which include:

• type and parameters of the coolant;
• classification of buildings;
• adjustment parameters;
• installation location in the system;
• purpose of the system.

The types of heating systems depend on the coolant used in them. This could be water, steam, antifreeze. The performance of the system will directly depend on them.

The type of building where the balancing valve will be installed is of great importance. The location of the valve is also important - the supply and return pipelines have very wide differences between each other. Therefore, the balancing devices installed on them will also be different.

The purpose of the system is very important. According to their characteristics, hot and cold water supply and heating systems have quite large discrepancies. For example, in DHW system Only thermostatic balancing valves are used. Therefore, the choice of balancing valve is not the same simple matter, as it seems at first.

Principle of operation

The valve structure is clearly visible in the figure. But what is the principle of its operation, this needs to be understood.

Turning the adjustment handle changes the position of the valve spool. As a result, the size of the section between it and the saddle changes.

Thus, the coolant, passing through a large or small section of the valve, changes its pressure as it changes throughput. Thus, by adjusting the pressure, it is possible to achieve uniform heat distribution for each heating device.

For automatic adjustment For heat distribution, two balancing valves are installed in the system - on the input circuit and in the return circuit. They are connected to each other. The balancing effect of the system will take place automatically.

But to do this, you will need to correctly adjust and configure the entire heating system at the very beginning, at the first start. If all the manufacturer's requirements are met, the balancing equipment works flawlessly.

Note: Some people mistakenly, on the advice of local “Kulibins,” try to install a ball valve instead of a balancing valve. The absurdity of such an idea becomes obvious immediately after the system is launched. The valve does not relate to the control valves on any side.

Installation

The insertion rules are simple, but you must follow them all. Otherwise, the desired effect will not be achieved.

When performing installation, you must perform the following operations:

• check the installation of the system;
• cut a thread at the valve installation site;
• prepare the valve for installation;
• install the valve in its place in the system;
• install in front of the valve.

After installing the balancing valve, it must be adjusted. This process is accessible only to specialists and requires special equipment and knowledge.

Take into account: You shouldn’t even try to install a heating balancing system yourself. IN best case scenario the system will not give the expected effect, in the worst case, you will have to redo the heating system.

Control valves are produced by several manufacturers. Among them, one of the leading places belongs to such well-known companies as Danfoss (Danfoss), Broen, Meibes. The list can be continued.

A wide selection allows you to navigate by price and quality. Parameters such as quality and reliability provide the consumer not only with comfort, but also ultimately with significant savings.

Any heating system must be configured properly. the main objective such setting is to ensure the same performance in all parts of the network. For example, if it is a heating system multi-storey building, then there should be heat on both the top and bottom floors. These indicators should not only be equivalent, but also close to the normative ones. One of the most effective ways settings is the use of a balancing valve, the installation of which should ideally be thought out at the stage of creating a heating system project.

Peculiarities

Modern systems heating systems are characterized by uneven heat distribution over separate rooms. The amount of heat depends on the coolant flow, and the water flow is controlled by the balancing valve. If you do not use this device, the amount of heat received will decrease, moving away from its source. Accordingly, there will be different temperatures at different points in the network.

Previously in simpler systems this problem was solved by installing pipes with certain diameters or installation of special throttle washers. The latter are characterized by a certain passage size, which ensures the flow of the required volume of water.

However, in order to achieve the required volume of coolant, it was necessary to stop the flow and disassemble the pipes. Today, a balancing valve is used to bring water flow to the standard.

The design is a specific valve with which the flow of coolant is regulated. Sometimes as a supplement to this mechanism two fittings are built in, which measure the pressure in different zones in relation to the control mechanism. Additionally, it connects to a capillary tube to coordinate with other controls.

There are two types of these valves: manual and automatic.

• The first type, as you might guess from the name, is controlled manually. The products are inexpensive and therefore are the most common. By changing the pressure difference and water flow, they are able to adjust both individual sections and the entire system. In addition, at control points it will be possible to monitor the indicators of the working environment, and in the event of a breakdown, turn off any fragment and arrange renovation work. Unfortunately, the adjustment of such valves is carried out under the condition of a constant flow of coolant. If it changes, the system will not be able to function. Therefore, it is better to install such models in private homes and with a simplified heating system.

• Automatic valves are devices that do not require human intervention to operate. They independently regulate the volume of coolant spent or the pressure difference. Some models can work together using impulse tube, simultaneously controlling both flow and pressure difference. It is also worth adding that very often measuring instruments are attached to balancing valves to make debugging the system less complicated.

Automatic devices are attached to both the inlet and return pipelines. They are connected to each other by a thin tube, thanks to which the valve moves and shuts off the flow of water depending on pressure surges. Such a device is configured once and does not require further adjustment.

Valve models may differ depending on the heating medium (steam, water or glycol solution), type of building ( a private house or an ordinary high-rise building), installation location (on the supply or return pipeline), operating environment (at what pressure, temperature and volume of distilled water the device operates). Finally, valves can exhibit other properties, for example, regulate pressure and be equipped with additional devices, such as a measuring diaphragm.

Valves are usually made from brass and cast iron (for manual models) or a combination of these materials with carbon steel in the case of automatic versions. It is also worth adding that they can be installed on “warm floors” and on air conditioning pipes with water supply.

Principle of operation

Balancing will have to be done in the following cases:

• Initially, mistakes were made at the design or installation stage of the heating system;
• there was a radical replacement of batteries with those that do not correspond to the design;
• the pipeline design has changed;
• the system, due to lack of timely cleaning, became clogged.

Even one of the above situations can lead to problems with heating: oxygen-hydrogen plugs, temperature deviations and excessive consumption of energy required for heating will occur. As a result, apartment residents will become very uncomfortable in the premises.

You should begin installing the valve only after understanding the purpose of the device, as well as how it works. In short, the handle rotates - the section size changes due to the fact that the spool has blocked the flow. The cross-section has decreased - the hydraulic resistance has increased - the flows in different pipes have been leveled out.

If in the apartments of a multi-storey building individual radiators are not installed thermostatic valves, and the amount of heat supplied to each room must be constant and calculated in advance, then a manual balancing valve will need to be installed. This part is mounted on the return pipeline at the point where the pipe separate apartment connected to a common line, just like ball valves.

The circuit with a balancing valve is easily implemented when the number of radiators does not exceed five. However, if there are more of them, then a situation may well arise when the flow in one heating device is blocked, but increases in another. As a result: some will overheat, while others will remain insufficiently warm. In addition, if the room is equipped with thermostatic controls, the water flow will change regularly.

In this case, it will come to the rescue automatic regulator. The combination of data on pressure drops in the system and water volume will allow you to quickly respond and keep the system in balance.

The automatic balancing valve is adjusted using a table of differential pressure and flow, as well as a flow meter.

Installation

The balancing valve, designed to control the heating system, is very easy to install with your own hands. Installation is carried out as if installing a regular ball valve. In principle, it is not particularly important how the valve itself will be placed in space, but the arrow on the body must correspond to the direction of water flow. Otherwise, the valve will begin to create resistance to the coolant. The temperature and pressure of different valves may vary, so by studying the characteristics of your own heating system, it is better to find the most suitable option from manufacturers.

It is necessary to place special protection in the form of a filter in front of the valve. This device will prevent debris and dirt from getting onto individual elements of the regulator. In addition, it is recommended to install the valve so that there are significant gaps of straight pipe before and after it. This will prevent the appearance of bends that affect the movement of water. Also, before starting installation, the pipes must be flushed.

Installation of the valve begins after checking the condition of the pipes is completed - it is necessary to check their integrity and the absence of debris. Then the location where the device will be placed is determined. The parameters of the straight pipe sections before and after the valve must correspond to the following figures: five diameters before the element and two diameters after the element or even more, this will eliminate turbulence.

Then the valve is screwed into the thread of the pipe, previously equipped with tow.

Threading on the pipe can be done with a die or other similar tool. For a quality connection to the valve to occur, the thread length must be up to seven turns.

• Adjustments can only be made once the calculated readings are received. You can obtain the latter from the thermal system design documents. The setting is carried out in accordance with the valve diagram and the obtained values. Rotating the handle sets the spindle in motion, which in turn makes adjustments.
• If a radiator thermostat is installed in an apartment, this means that it will constantly change the volume of coolant, depending on the slightest fluctuations in the temperature in the room. In this case, you immediately need to install an automatic balancing valve, the second name of which, by the way, is “dynamic”.
• It is important to follow the flow direction indicated on the valve body.
• During installation, care should be taken to ensure that no debris or unnecessary objects get inside the pipeline. Otherwise, the operation of the device may be impaired.
