H142X hydraulic level control valve

H142X hydraulic water level control valve is a hydraulic control valve which automatically controls water tank and water column level. When the water fall by more than the preset value, the floating ball valve is opened, the piston chamber pressure is reduced, piston top and bottom formation pressure difference, under the action of the differential pressure valve open water supply operations; When the water level rises to the preset height, the float valve is closed, and the pressure of the chamber chamber on the piston is increasing and the disc shuts off the water supply. This reciprocating automatic control liquid is set at a height to realize automatic water supply.
