GKV57NC non-slam check valves is a diaphragm-type control valve that can adjust the speed of open and the close through the hydraulic, when the inlet pressure rises above the valve opening pressure, the valve slowly open

GKV57SL solenoid control valve is mainly controlled through the solenoid valve for opening or closing the valve. The valve consists of a basic valve and a solenoid switch, which controls the liquid in the gas chamber by

GKV57DR light pressure differential bypass valve is fully automatic, hydraulic control valves. It is designed to maintain the pressure differential between the two lines in order to avoid pipeline pressure differentials

Multi-function valves can be used to achieve more functions on the same valve body. First of all, it can be used as a muffler check valve, and also can be used as an on-off valve. In addition, it can achieve the function

GKV68PD pulsation damper of the pressure inside the shell is installed in a similar separation air bag. An inert gas (nitrogen) with a pressure of P0 comes into the bladder through the inlet valve until the air bag expan
