What kinds of balancing valves are available? What is it for?

Balance valve there are several, early out of the static balance valve, can be manually adjusted, can be connected to the instrument to measure resistance and converted into flow, is a local resistance coefficient can be adjusted the valve. It is usually located on the main pipe, or the more demanding one can be located on the main pipe or the entrance of the equipment. The disadvantage is that the system resistance can only be balanced at the rated flow, the hydraulic balance is affected when the end of the electric valve to change the resistance.

In the 1990s out of the dynamic balance valve used in the system pressure changes under the occasion of constant flow, that is, the flow does not change with the change of system pressure, so called dynamic balance valve. Its use is obvious, can only be used in a constant water flow system, not with electric valves.

These two kinds of domestic valves were made in the early stage by China Air Conditioning Research Institute. Genius valve

FLOWCON dynamic balancing electric control valve from Denmark is a newer generation product. It combines electric valve and dynamic balance to adjust the preset flow of dynamic balance when the electric control valve is adjusted. For example, when the electric control valve adjusts the flow to 50%, the valve can maintain a constant flow at the 50% flow point. This is the only one in the world that has this product. It is used at the end of the air conditioning unit where the electric valve was originally located. Other hydraulic balancing measures for the main and branch pipes (including the same way pipe) can be eliminated.

The brief introduction cannot explain the difference of various valves very well. The following xiao Qi summarizes the source, characteristics and types of various valves in detail. Only to understand the characteristics of each valve, in order to more clearly distinguish the various valves.
