Dimensions:
2” (DN50)-16” (DN400)
Design Standard:
JB/T 10674,ASME B16.1 CL 125
Connection Standard:
ASME B16.1 CL 125
Working Pressure:
300PSI, 250PSI, 200PSI, 175PSI
Application:
The pump control valve is mainly applied in the waterworks system, working temperature is from 0℃ to 80℃
The pump control valve is a diaphragm type hydraulic control valve which uses the hydraulic pressure of the pipeline as the driving source. When the system works normally and the pressure in front of the valve is greater than the pressure behind the valve, the valve is fully open. When the pressure behind the valve exceeds the pressure in front of the valve, the valve will be closed at a controlled speed to prevent backflow and protect the water pump. The valve can open slowly, close quickly, close slowly and eliminate water hammer integration without system pressure fluctuation.
