Differential Pressure Regulating Valve DPAV Series

DPAV Differential Pressure Regulating Valve adjusts the pressure difference when the inlet and outlet pressure difference is lower than the set pressure value, and opens or closes according to the set pressure difference value. It is suitable for the pressure adjustment of the liquid supply pump or can reduce the pressure of the medium line.

DPAV

DPAV-1N

DPAV-1N Differential Pressure Regulating Valve(Solenoid Fully Open),which adjust when power is off,which adjust pressure difference when the inlet and outlet pressure difference is lower than the set pressure value.It is suitable for the relief pressure adjustment of the liquid supply pump or can reduce the pressure of the medium pipeline. When the power is on, the main valve open fully to make the outlet get a larger flow and pressure.
