The self regulating valve is a new valve types. Compared with the manual control valve, and its advantage is to automatically adjust; relative to the electric control valve, it has the advantages of no need of external power. The practical application proved that, in a closed water circulation system, such as hot water heating system, air conditioning chilled water system, the correct use of the valve, can easily achieve the flow distribution system; dynamic balance can be realized; can greatly simplify the debugging of the system; can stabilize the pump working condition.
