Large multi-circuit heating systems quite often encounter the problem of uneven heating different rooms. The coolant flows along the path of least resistance, which is why the farther from the heat source, the less thermal energy consumption than next to it. A manual or automatic balancing valve for a heating system (otherwise known as a valve) is used to equalize the coolant flow in different branches.
The design of the radiator element, which serves for manual balancing of heating branches, consists of the following parts:
- A body with threaded pipes used to connect pipes, made of brass. Using casting, a so-called saddle is made inside, which is a round vertical channel that expands slightly upward.
- A shut-off and regulating spindle, the working part of which has the shape of a cone, which enters the saddle during twisting, thereby limiting the flow of water.
- O-rings made of EPDM rubber.
- Protective cap made of plastic or metal.
Everyone has famous manufacturers Products come in two types - angular and straight. Only the shape has changed, but the operating principle is the same.
How a valve works in a heating system: as the spindle rotates, the flow area decreases or increases, thereby making adjustments. The number of revolutions, from closed to open, to the maximum level varies from three to five revolutions, depending on who the manufacturer of the product is. To turn the rod, use a regular or special hexagon-shaped key.
Compared to radiator valves, main valves have a different size, an inclined spindle position, and excellent fittings, which are necessary for:
- to drain the coolant if necessary
- connecting metering and control devices;
- connecting the capillary tube coming from the pressure regulator.
It is also necessary to mention that not every system needs balancing as such. For example, 2-3 short dead-end branches, equipped with 2 radiators on each, can immediately enter normal operating mode, provided that the diameter of the pipes is selected accurately and the distances between the devices are not very large. Now let's look at 2 situations:
- There are 2-4 heating branches of unequal length leading from the boiler, the number of radiators on each is from 4 to 10.
- The same thing, only the radiators are equipped with thermostatic valves.
Since the bulk of the coolant always flows along the path with the least hydraulic resistance, in the first case, most of the heat will be received by the first radiators, which are closest to the boiler. If the flow of coolant to these batteries is not limited, then those located at the very end of the batteries will receive the least amount of thermal energy, and thus the difference between temperature conditions will be 10 ° C or more.
To ensure that the farthest batteries are provided required quantity coolant, balancing valves are installed on the connections to the nearest radiators from the boiler. By partial overlap internal section pipes, they restrict the flow of water, thereby increasing the hydraulic resistance of a given section. In a similar way, the supply is regulated in systems where there are 5 or more dead-end branches.
In the second case, the situation is somewhat more complicated. Installation of radiator thermostats makes it possible to change the water flow automatically if necessary. On long branches with big amount heating devices that are equipped with thermostats, balancing valves are combined with automatic differential pressure regulators.
The latter, using a capillary tube, are connected to a balance valve, react to a decrease or increase in coolant flow in the system and maintain the return pressure at the required level. Thus, the coolant is evenly distributed among consumers, despite the fact that the thermostats are activated.
What types of balancing valves are there?
Standard ball valves for heating radiators are unable to regulate the distribution of thermal energy in pipes and radiators. But nevertheless, in order to distribute heat evenly in the rooms, such adjustment is simply necessary.
There are two types of balancing valves - manual and automatic. Manual ones are necessary in order to configure the network during its installation, and automatic ones change the parameters of the heating network at the time of heating.
When selecting a valve, you need to take into account many characteristics, which include:
- type and characteristics of the coolant;
- installation location in the system;
- adjustment characteristics;
- adjustment parameters;
- classification of buildings;
The types of heating systems directly depend on the coolant they use. It can be antifreeze, steam, water. They directly affect the performance of the system.
An important characteristic is the purpose of the system. The parameters of hot and cold water supply and heating systems differ quite greatly. For example, in DHW system Only thermostatic balancing valves are used.
The type of building where the balancing valve will be installed is of great importance. The installation location of the valve also plays a fairly important role, since the return and supply pipelines differ quite significantly from each other in characteristics. And because of this, the balancing devices that will be mounted on them will have significant differences.
Where and when is the main valve installed?
Most private homes use manual radiator valves. They are quite enough for normal adjustment of water heating in cottages whose area does not exceed more than 500 m². Installation Installation of main-type balancing valves in the heating system is done in the following cases:
- in buildings where an extensive heating network with a large number of risers is installed;
- V apartment buildings, which are heated by their own boiler room;
- when connecting a solid fuel boiler with a heat accumulator.
Once you have an idea of the purposes of balancing valves, you need to understand the specific locations of their installation. Radiator valves must be installed at the outlet of the heater, that is, on the return line, and main valves must be installed on the pipeline that brings cooled water from consumers to the boiler room. In the case when the element is paired with an automatic pressure regulator, it can be installed both in the return and supply pipelines, depending on how the circuit itself is designed.
Note: aluminum and steel radiators With bottom connection are already equipped with a balancing tap, which is built into the special fittings that are necessary to connect the connections to such devices.
We list the points in which it is not necessary to install control valves:
- in short-term dead-end systems, which have identical hydraulic “shoulders”;
- in the case when the batteries are equipped thermostatic valves with preset;
- in collector-type heating systems.
- on the last (dead-end) heating radiator;
Temperature regulators with presetting, which are located at the water supply to the battery, also act as a balance valve, so at the output heating device it is necessary to install a shut-off ball valve. Such fittings are installed on the connections to the last radiator in the chain, since there is no particular point in adjusting it, and it must be completely open.
How to balance a heating system?
As a rule, heating system installers determine the coolant flow in the batteries quite simple method: the number of revolutions of the balancing valve is divided by the number of heating devices and thus the adjustment step is calculated. Moving from the last radiator to the first, the taps are tightened with the resulting speed difference.
For example, one arm of the dead-end system is equipped with 5 radiators with manual valves for 4.5 spindle turns. 4.5 must be divided by 5, as a result we get approximately 0.9 revolutions. And thus the penultimate device must be opened by 3.6 turns, the third by 2., the second by 1.8 and finally the very first by 0.9 turns.
The method is very approximate and takes into account different radiator powers, and is therefore used exclusively as a preliminary setting with adjustments during operation.
During installation, the following manipulations must be performed:
- check the system installation;
- in the place where the valve is to be installed, it is necessary to cut a thread;
- prepare the valve for installation;
- install the valve in its place in the system;
- A filter must be installed in front of the valve.
After the balancing valve is installed in the heating system, you need to begin the process of setting it up. This operation can only be carried out by specialists, as it requires additional knowledge and equipment.
Step-by-step instructions for balancing can be presented as follows:
- All balancing valves must be opened to the limit and the system brought into operating mode, whose supply temperature will be 80°C.
- Using a contact thermometer, it is necessary to measure the temperature of all heating devices.
- In order to eliminate the resulting difference, it is necessary to close the taps of the first and middle batteries; there is no need to touch the end ones. The near heating radiator must be opened by 1-1.5 turns, and the middle ones by 2-2.5.
- The system will take about 20 minutes to adapt to the new settings, after which it will be necessary to take measurements again. The main task is to achieve a minimum temperature difference between the nearest and farthest radiators.
Note. Weather and outside temperature do not matter, the only important characteristic is the difference in heating of the batteries.
Installation of balancing valves is necessary for large heating systems. They help to optimally distribute the coolant throughout all circuits. For such equipment, correct operation is achieved correct installation and setting. The installation of valves should only be considered when designing the system.
To the owner of the house who is engaged in self-installation equipment for heating system, you will certainly have to face a balancing act. It is quite easy to implement if all devices except the last one have balance valves.
The best choice would be models that can be easily adjusted with a screwdriver or wrench, rather than using a plastic handle that children can reach. Perhaps in winter period you will have to adjust the position of the spindles, since heat loss in the rooms varies.
Advice: there is no need to make sudden movements, and open taps in cold rooms slowly by ¼ turn.
The larger the heating system, the more difficult it is to ensure uniform distribution of heat to all rooms without exception, no matter what distance from its source they are located. To ensure uniform temperature conditions, adjustment mechanisms are built into the heating network in different areas. heat flow. The most common and effective of them is the balancing valve in the heating system.
- durable brass body, equipped with pipe connections, with a saddle located inside in the form of a special vertical channel;
- a cone-shaped spindle screwed into the seat body to regulate the coolant flow;
- rubber sealing rings;
- plastic (less often - metal cap).
- determination of intrasystem pressure on both sides of the valve;
- connection of a capillary type tube.
- fluoroplastic;
- dense rubber;
- metal.
Show all
general characteristics
There are several types of methods by which heat flow is regulated. The first of them uses pipes different diameters regulating the volume of coolant passing through the radiators. Another one is based on the use of special washers that correct the passage of the required amount of heated water in this area.
A detailed description of these methods is not of interest, since they are already outdated and not used. Modern mechanism adjusting the coolant supply is the heating installation balancing valve consisting of:
The main part of the device is two special fittings responsible for:
Each of the fittings has a pressure meter, and if there is a difference in values, you need to calculate the rational amount of water flow.
Balancing valve VT.054
Operating principle
The principle of operation of a balancing valve in a heating system is to adjust the cross-section of the passage opening for the coolant inside the pipeline. Using the working elements of the valve, you can adjust the heating system at any time without stopping its operation, and achieve a comfortable thermal regime in heated rooms at minimum consumption energy.
Rotation of the adjusting handle causes the spindle to move down or up, respectively opening or closing the passage hole in the pipe or reducing its cross-section. Reducing the cross-section of the throughput hole creates an obstacle to the movement of water, artificially increasing the flow speed. As a result, water reaches remote circuits faster and with less heat loss. This ensures uniform heating of all rooms.
With constant changes in operating pressure, it is important to ensure reliable tightness of the connections inside the valve. For the production of spindle o-rings, use:
Danfoss manual balancing valves. Hydraulic balancing engineering systems
Types of valves
There are two types of valves: manual and automatic. Each of them has its own advantages. Manual balancing valve is more suitable for heating pipelines small sizes with stable pressure, usually installed in individual residential buildings and apartments. Here balancing valves are installed on each radiator.
In addition to individual configuration of each battery, if necessary, such a configuration provides repairs individual elements systems without turning it off completely. Another advantage of a manual valve compared to an automatic one is its lower cost.
Automatic crane
Automatic devices for adjusting the flow of coolant are much more expensive than manual valves. They are installed on risers of heating systems apartment buildings, administrative buildings or industrial premises.
The operating principle of an automatic valve is not the same as that of a mechanical faucet. With manual adjustment, the amount of coolant passing through the pipe per unit time depends on the flow area, which is set using the valve.
And in automatic system the valve is constantly set to maximum water flow; the pressure and amount of coolant supplied to the pipeline is regulated using thermostats and capillary tubes installed on the radiators.
Balancing valve with internal thread STAD
Installation of balancing valve
Each balancing valve has an arrow on the body that indicates in which direction the liquid inside the body should move in order to minimize turbulence that affects the correct settings. The arrow serves as a guide when installing the mechanism on the pipeline.
The device is installed on straight sections of pipes so that the length of the flat part of the pipe in front of the valve is at least five times its diameter and at least two at the outlet. It needs to be mounted in the return branch of the system; for this you only need a plumbing adjustable wrench.
During installation work several rules must be followed consistently. First, a mandatory check is carried out, followed by flushing and cleaning the pipeline from the possible presence of metal shavings or other foreign objects in it.
If the device has a removable head, it must be removed before installation, following the instructions. This makes installation of the valve easier. Then one end of the tap is screwed onto the pipe. The other end is connected to the radiator through a coupling. To seal the threads, it is necessary to use threads made of flax fiber impregnated with a special lubricant.
Manual balancing valves - master class
Setting methods
After installing the balancing valve in the heating system, it must be set to energy-saving mode. To do this, each valve is supplied with instructions for calculating the optimal number of handle revolutions. The valve can be adjusted in two ways.
Professionals use a simple and time-tested method. By dividing the number of valve revolutions by the number of radiators, they determine the adjustment step of each tap. So, if the spindle speed is 4.5, and the number of radiators is 10, then the step is determined to be 0.45 revolutions. The system will be optimally adjusted if each valve, starting from the last radiator, is open by plus 0.45 turns.
For the faster and more accurate second method, it is necessary to use a contact-type thermometer. To adjust, you will need to heat the system to 80 degrees with all valves open and measure the temperature of each radiator separately. Temperature discrepancies are eliminated if you tighten the first and middle taps. Usually 1.5 turns are enough for the first valve, and 2.5 turns for the middle ones. After letting the system adapt, take control measurements after half an hour.
The use of both methods eliminates temperature differentiation when heating radiators and promotes uniform heating of all rooms with minimal thermal energy consumption.
Installation of balancing valves in the heating system ensures uniform heating of all rooms without exception and economical consumption of energy resources. This is especially necessary for large heating systems. This device best helps distribute the coolant along its contours. But technology installation work should be considered even when designing a heating system, since the quality of the valve’s operation depends on its correct installation and configuration.
The efficient operation of the heating system is largely determined by its balance. It allows you to prevent the possibility of situations when an excess volume of coolant is supplied to one radiator, while an insufficient amount is supplied to another. To do this, the heating system must include Danfoss balancing valves, the operating principle of which allows for hydraulic balancing (linking) of coolant flows according to various elements heating system or stabilize circulation pressures or temperatures in them.
If necessary, it is possible to install pipeline throttling valves from other manufacturers, which will eliminate instability of the heating system, difficult startup of the system, uneven distribution coolant and the associated uneven heating of the premises.
What types of valves are there?
Balancing valves are usually divided into:
- automatic (dynamic), which are capable of maintaining a constant pressure drop in two-pipe risers or flow rate in risers single pipe system heating;
- manual (static), which can be used as an adjusting diaphragm in systems where there is no automatic control device or where the installed regulator does not allow limiting the flow limit. They are valve type devices.
Balancing valve made of brass
It should be noted that all modern systems heating systems that use radiator thermostats are dynamic systems. As a result of the operation, radiator thermostat, constantly responds to the slightest changes in air temperature in the room, thereby changing the coolant flow, which leads the heating system to a constantly changing (dynamic) operating mode. This operating mode necessitates the use of automatic (dynamic) balancing valves.
It is also common to classify valves depending on:
- used working environment: water, glycol solution, steam;
- working environment parameters: pressure, flow, temperature;
- installation locations: supply or return pipeline, bypass;
- type of building (single-family or public);
- operating function, which provides for the regulation of pressure, temperature, and flow of the working medium. A combination of them is also possible;
- type of connection, which can be threaded or flanged.
Can be used to make valves various materials. Static valves are usually made of brass (can be flanged or threaded connection) or cast iron (flange connection only). In the manufacture of dynamic products, brass, cast iron or carbon steel can be used to ensure the required technical characteristics.
For ease of regulation, the valves can be equipped with:
- fixed position lock;
- shutter position indicator and setting value;
- pipe for drainage of the area on which the valve is mounted
- a measuring diaphragm that allows for highly accurate flow determination;
- pipes for measuring coolant flow, pressure and pressure drop across the valve.
Valve operating principle
The main difference between a balancing valve and a shut-off valve is that it can operate when the valve is in an intermediate position. It is worth noting that design balancing valve may be different. There are valves in which the stem is located at an angle relative to the flow, and the spool is made not only straight, but also cylindrical, conical or radial. Let's look at the operating principle of a valve that has a straight stem and a flat spool.
Straight stem valve
During valve operation, the flow area between the spool and seat pair changes. Due to this, a balanced system is achieved. The spool is located in a plane parallel to the axis of the pipeline. While in a plane located perpendicular to the perpendicular axis of the pipeline, there is a threaded spindle to which the spool is pivotally connected. The valve body contains a fixed threaded nut, which together with the spindle forms a running pair.
Due to the rotation of the tuning handle, torque is transmitted through the spindle and the fixed threaded nut associated with it, as a result of which the spool is given a translational movement, as a result of which it moves from the lowest to the highest position. Being in the lowest position, the spool is tightly connected to the seat in the valve body, thereby tightly shutting off the flow.
Depending on the type of coolant used, hermetic shutoff of the flow is ensured by the presence of a seal between the valve and the seat, created by fluoroplastic or rubber rings or of the metal-to-metal type. As a result of a change in the flow area, the throughput of the balancing valve changes, which is understood as a value numerically equal to the flow rate, expressed in m³/h, through completely open valve, at which the pressure loss will be 1 bar. The dependence of throughput on changes in gate position can be seen in technical specifications valve
BALLOREX valves
The Polish company BROEN BALLOREX, in its Venturi series, produces a manual balancing valve with high accuracy regulation. Such a valve is a valve that performs two functions:
- valves with manual adjustment;
- shut-off ball valve.
It allows for balancing and hydraulic regulation, limiting flow, opening and closing the flow of the working medium in the system, as well as measuring the temperature of the working medium and flow using a standard flow meter. It can be purchased in various designs. The line of these valves is available with a nominal diameter from DN 15 to DN 200 and a nominal pressure of PN 16 Var and PN 25 Var. Valves with a nominal diameter from DN 15 to DN 50 and a pressure of 16 Var have a flange connection, and valves with a pressure of PN 25 Var have a threaded connection.
BROEN BALLOREX valve
All balancing valves and their elements (valve body, measuring diaphragm, shut-off ball, adjusting rod) with a nominal diameter from DN 15 to DN 50 are made of chrome-plated brass. And balancing valves with a nominal diameter from DN 65 to DN 200 are made of steel also with a flanged or threaded connection.
Valves of the Venturi series, with the same nominal diameter, are produced with different flow capacities, depending on the type of design: high (H), standard (S) and low (L). In addition, the Venturi series is available in two types: Venturi FODRV and Venturi DRV; these valves have flow control measuring nipples. All valves from this company can be installed in any position on any section of the pipeline before or immediately after a branch, before or after a narrowing of the pipeline.
This Polish company also offers automatic balancing valves in various modifications. Ballorex DP valves are installed on the return pipeline, providing the required pressure drop on the circulation ring under any load. This makes it possible to put the facility into operation step by step due to the possibility of zonal balancing. The use of Ballorex DP eliminates noise phenomena caused by overpressure created in other parts of the heating system.
Valves from a Danish manufacturer
Another manufacturer is the Danish company Danfos, which supplies valves of all types, differing high quality execution. MSV-BD LENO™ manual valves are a new generation of valves. They allow solving problems of hydraulic balancing of heating systems. In doing so, they combine the functions of a standard manual valve and a ball valve, thereby ensuring fast and complete shut-off of the flow. Most models allow you to take data at the output and input, however, individual models The nipple is provided on one side only.
Automatic valve ASV-M
The automatic ASV-M, the price of which suggests an optimal price-quality ratio, can be used as a shut-off valve and, if necessary, connecting an impulse tube from the ASV-P(V). ASV-I. It allows you to limit the maximum flow rate of the transported coolant. The valve is equipped with special plugs for measuring nipples. By installing nipples, you can measure the coolant flow that flows through a specific section of the system.
Valves of the ASV series are distinguished by high quality workmanship. They allow you to maintain a constant pressure difference between the supply and return pipelines. The ASV-P, installed on the return line, features a fixed setting of 10 kPa. While the ASV-PV has a measurable setting of 5-25 kPa, the ASV-PV Plus has a measurable setting of 20-40 kPa.
How is installation done?
When performing installation, it is very important to ensure the required position of the valve. In this case, the arrow on the body must coincide with the direction of movement of the coolant. This situation will provide not only the necessary design resistance valve, but also the required flow. At the same time, it is worth noting that some manufacturers allow the possibility of installing the valve not only in the direction, but also against the flow. The rod, in most models, can occupy a different spatial position.
During the installation process, it is worth protecting the working parts of the fittings from various mechanical contaminants. To do this, you need to install a sump filter or a special filter in front of the valve. To eliminate turbulent fluid movement, it is necessary to provide straight sections of sufficient length before and after the valve. This requirement must be specified in the documentation for the valve.
A heating system equipped with a balancing valve must be filled in a special way. To do this, in systems equipped with dynamic valves, it is necessary to provide filling connections, which must be located in close proximity to the valve on the return pipeline. And the valves mounted on the supply pipeline must be carefully closed. To set the balancing valve, a special flow meter or differential pressure and flow tables are used. However, in any case, the initial calculation is performed at the stage of calculating the heating system.
Good day to everyone who reads this post! In it I will tell you about balancing valves for heating systems. Let's start by figuring out why a balancing valve is needed in a heating system.
Why is a balancing valve needed?
In modern large systems heating systems, there is often uneven heating of different rooms. This is due to different coolant flow rates through the branches of the heating system. Coolant (as electricity) tries to flow along the path of least resistance, therefore, at a great distance from the heat source (thermal unit or boiler), the flow rate should be less than near it. In order to equalize the coolant flow through different branches, balancing valves are used.
As can be seen from the top figure, the flow rate in heating circuits of different lengths will be different and the temperature in the rooms will also be strikingly different. Now let's talk about the types of balancing valves.
Types of balancing valves.
Balancing valves come in two main types:
Danfoss made a very interesting video about the operation of manual balancing valves. I advise you to watch this video from beginning to end. It shows unexpected patterns of operation of this type of valve:
From the figure it is clear that internal organization An automatic balancing valve resembles a piston pressure reducer, but the functions of these devices are completely different. I bring to your attention two videos on this topic:
To simplify the setup of heating systems, special measuring instruments, which simplify and speed up system balancing. Look at the picture below:
Installation of balancing valves.
The installation of a balancing valve is carried out in the same way as the installation of ball valves. The position of the valve in space does not affect its operation, but you need to pay attention to the arrow, which indicates the recommended direction of flow. If it is mixed up, the valve will create greater resistance to the flow of coolant. Valves can be installed on both supply and return pipelines.
Operating temperature and pressure may vary depending on the specific model, so it is best to select the equipment you need using manufacturer catalogs. You can find them on the official websites of manufacturers.
Summary.
Installation of balancing valves is necessary in large heating systems. They allow optimal distribution of coolant throughout all circuits. For the operation of such equipment, it is important correct installation and subsequent setup. It is necessary to consider the installation of valves at the design stage of the system. That's all, I'm waiting for your questions in the comments!
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 costs for the heating system are guaranteed.
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 required quantity 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 input hot water, those 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. The temperature will even 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
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 a domestic hot water system only thermostatic balancing valves are used. Thus, choosing a balancing valve is not as simple as it seems at first.
Principle of operation
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 the throughput changes. Thus, by adjusting the pressure, it is possible to achieve uniform heat distribution for each heating device.
To automatically adjust the heat distribution, two balancing valves are installed in the system - on input circuit and in the return. 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
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.
