Pneumatic Three-way Type Control Valve(ZJHQ,ZJHK)
Summary:
ZJHQ and ZJHX pneumatic diaphragm three-way control valve is a special three-way control valve developed for three-way control. There are two structural forms of confluent flow and diverging. The valve core structure adopts the cylinder thin wall window, and the side direction. It has the adjustment accuracy high and the movement is stable reliable. Pneumatic diaphragm three-way regulating valve confluence type is mainly used to mix two kinds of fluids into a third kind of fluid; The shunt type is mainly used to divide a stream of fluid into two streams, which can replace two single-seat regulating valves that switch each other. It is used for regulation and control of liquid, gas, steam.
