Model &Name: ZJHP(M), ZSJP(M) Series Elaborate & Small Precision Diaphragm(Piston) Single-Seat (Sleeve) 

Control Valves

Characteristics:The actuator is zero adjustable in multi-springs; Low hydraulicresistance in valve chamber;

The connectionbetween valve plug and push rod adopts anti-rotating structure, with anequilibrium structure for 

Sleeve-type Control Valves and a large allowablepressure differential;

The selection ofDiaphragm ZJHP(M) and Piston ZSJP(M) is determined by the operation pressuredifferential, 

installation space and the air supply conditions.
