ZJHP (M) pneumatic single seat (sleeve) regulating valve

ZJHP (M) pneumatic single seat (sleeve) regulating valve
ZJHP (M) type pneumatic single seat (sleeve) regulating valve is composed of pneumatic multi-spring film actuator and low flow resistance straight-through single seat valve (sleeve valve). The core is a plunger type structure. Compared with ordinary single-seat valves, it has the characteristics of small size, light weight, and large flow rate. It is suitable for occasions with large flow rates and strict leakage requirements. Compared with ordinary sleeve valve, ZJHM type small sleeve has the characteristics of 1/3 small volume, light weight 1/3, and large flow 1/3. It is widely used in industrial process automatic control that requires low noise and large pressure difference. System.

1. This table is calculated on the basis of a standard specification implementing agency. If the maximum working pressure difference exceeds the listed range, it can be proposed to the factory and appropriate solutions are taken.
2. This table is based on the valve closing position. Therefore, there will be greater allowable differential pressure at other locations.
