Static balancing valve for heating systems. An overview of the features and applications of balancing valves from Ballomax. Features of manual balancing fittings

The functioning of the heating system is often accompanied by an uneven distribution of the coolant along the circuit and connected devices. This can lead to pressure and temperature fluctuations that adversely affect heating efficiency and can damage equipment. The balancing valve helps to prevent these consequences, various models which are implemented by Forsterm.

Manual balancing valve: principle of operation and purpose

This device is a type of pipeline fittings and is used for the calculated distribution of the coolant along the circuit and equalization of its pressure and temperature. Regardless of the design of the balancing valve, its principle of operation 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, in connection with which the device provides the possibility of smooth adjustment.

AUTOFLOW devices are able to automatically balance the hydraulic circuit, providing each terminal with the calculated flow. Even if the circuit is partially shut off due to actuation of the 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.

Assortment of balancing valves for the heating system

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

manual balancing valve - such a device is regulated by a valve and is operated in systems with constant pressure indicators, such as domestic heating and water supply;
automatic balancing valve - such fittings are equipped with electric or electrothermal actuators and are suitable for installation in systems with dynamically changing pressure, requiring fast and accurate response.

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

In heating systems it is simply required to be present static balancing valve. It is used to regulate and limit the heat carrier. With the help of such valves to save a large number of electricity.
The energy consumption that is needed for the presence of a particular temperature is consumed without exceeding it. In the presence of given element increases the life of the system and its continuous operation without failures.

Benefits of a static balancing valve

- Fixed valve setting.
- The presence of such an opportunity as to completely close the valve, with its subsequent reconfiguration.
- Easy to install, can be installed in any position.
- The highest ability to pass the coolant.
- Adjustment can be carried out according to the diagrams that are in the regulatory documents.
As we can see, the advantages of a static balancing valve are obvious, but that's not all. The main advantage is, namely, the valve can also be used in drainage. To do this, it is enough to install a nipple with a drainage function for measurement. This nipple is not included, it comes separately.

Installation and operation

- At the very beginning of work, the system must be thoroughly blown and washed. This is necessary to remove solid particles that could damage the static balancing valve seal.
- It is impossible for the valve to be acted upon by external and internal forces emanating from the pipeline.
— The valve can be mounted in any position, however the best option will be the location of the handle down.
— The static valve opens against the clock.
- It is strictly forbidden to use other levers.

Valve setting

It is very important to set the valve correctly for its proper functioning. Adjustment is carried out using a handle and two windows. To save the settings made, you need to remove the cover, which is located in the center of the handle, to give access to the screw, which is designed for adjustment. Once the flow rate is set, you need to fix it all the way. Then put back the cover. If necessary, this position can be sealed for fixation.
The flow rate that passes through the valve can be found using measuring instruments. Calculations must be made in the following order:
1. Connect the flow meter.
2. Select the desired units of measurement.
3. Take desired brand valve.
4. Choose the type and size.
5. Enter the current value.
6. Measure the flow.

The heating system needs periodic adjustment. The coolant must be evenly distributed over it, which means that the presence of special equipment, which will help to make the adjustment correctly. Such a device is often a balancing valve.

By hydraulic balancing, the coolant is distributed to all sections of the heating circuit without exception.

Simple system options involve adjusting the coolant flow by selecting the optimal pipe diameter around the perimeter.

Special washers are also used, the passage in which is designed for uninterrupted water flow, and uniform heating of the elements.

Each of these options has been used in heating schemes old sample. A new method is the installation of a balancing valve, which is a conventional valve that regulates the amount of coolant supply.

Design feature

A quality part includes reliable components:

Robust brass body with threaded fittings for connecting pipes. Inside the product there is a saddle in the form of a special vertical channel.
Adjusting spindle. The working part is represented by a cone that is screwed into the saddle. As a result of the spindle engagement, the coolant flow is blocked.
Rubber sealing rings.
Cap, usually made of plastic. There are also metal options.

A distinctive feature of the device is the presence of two special fittings.

They are responsible for the following functions:

Determine the pressure inside the system both before and after the valve.
Connect the capillary tube.

Each of the fittings measures the pressure, and if a difference in values is detected on the control mechanism, the water flow is calculated.

Operating principle

Balancing valves are designed to use them to achieve maximum efficiency of all heating elements of the system, as well as to adjust it at any time.

The Danish company "BROEN VALVE GROUP" appeared on the market of valve manufacturers in 1948. Today the company is considered one of the leaders in its segment. Fittings from "BROEN" are installed in heating systems and industrial highways.
