What is a balancing valve and what is its scope

When laying and assembling water and gas supply systems, various types of fittings are used, which have a specific purpose. One of its important elements are balancing valves (or valves).

Balancing valves and their modifications

The balancing valve (or valve) belongs to the class of pipeline fittings, the main function of which is to regulate excessive pressure in heating systems, ventilation systems, water supply and cooling systems. Valves are used for hydraulic connections of throttling rings and rings for circulating liquids or gas-air masses.

Such valves are divided into manual, automatic and combined type.

A manual balancing valve (for the aquatic environment) is used in systems where static hydraulics are installed. Automatic valves are designed for systems operating on dynamic hydraulics. In such systems, balancing is necessary in connection with possible pressure drops and the need for its regulation.

Incorrect circulation of water in heating systems is fraught with many unpleasant consequences. If there is a small head and water shortage in radiators and a boiler, firstly, there will be a low temperature in the room, and secondly, this will cause corrosion of the boiler itself. And if the temperatures are too high (if there is no balancing valve in the system), there is an outside noise in the batteries and pipes. Therefore, the valves are always installed on collectors and risers. Do not dispense with them and heat points.

To connect to other parts of the valve, the balancing valve is provided with an internal or external thread. The maximum temperature mode of operation is up to 120 degrees above 0, and up to 20 degrees below 0 (on a Celsius scale). The valves are equipped with drainage devices, pressure measurement indicators and setting inhibitors.

Gates from Danfoss

The market of sanitary fittings presents the widest choice of different parts and elements. One of the most popular manufacturing companies is the Danfoss company Danfoss. It produces a balancing valve of such a sought-after brand as "MSV-BD".

The products produced are among the newest type of balancing valves, which are involved not only in heating and cooling systems, but also in GVSs. They organically combine the properties and capabilities of both a valve and a ball valve.

The Danfoss balancing valve has a number of advantages compared to similar products:

• Simplicity of all kinds of settings;
• Convenient location of the scale of indicators, allowing you to see the setting from any angle ;
• Two measuring nipples;
• Additional drain cock, which allows two-way drainage;
• To open and close the valve in case of unforeseen situations, you can use the Allen key;
• There is an indicator on the handle indicating the position of the valve in the system "open" / "closed".

A portable water meter is used to set the correct operation of the balancing valve. This can also be done by relying on water temperature or hydraulic calculations.
