Overview
The Shangming brand ZJHP (M) pneumatic single seat (sleeve) regulating valve consists of a pneumatic multi spring thin film actuator and a low flow resistance straight through single seat valve (sleeve valve). The pneumatic single seat sleeve regulating valve has a straight through single seat valve body with a guide structure on the cover, and a plunger type valve core. Compared with ordinary single seat valves, it has the characteristics of small volume, light weight, and high flow rate, and is suitable for situations with high flow rate and strict leakage requirements. Compared with ordinary sleeve valves, the ZJHM type precision small sleeve valve has the characteristics of 1/3 smaller volume, 1/3 lighter weight, and 1/3 larger flow rate. It is widely used in industrial process automatic control systems that require low noise and large pressure difference.

Pneumatic single seat sleeve regulating valveProduct Overview:
The Shangming brand ZJHP (M) pneumatic single seat (sleeve) regulating valve consists of a pneumatic multi spring thin film actuator and a low flow resistance through single seat valve (sleeve valve). The single seat valve body is directly connected to the single seat cover with a guiding structure, and the valve core is a plunger type structure. Compared with ordinary single seat valves, it has the characteristics of small volume, light weight, and large flow rate, and is suitable for situations with high flow rate and strict leakage requirements. Compared with ordinary sleeve valves, this pneumatic regulating valve has the characteristics of 1/3 smaller volume, 1/3 lighter weight, and 1/3 larger flow rate. It is widely used in industrial process automatic control systems that require low noise and large pressure difference.

1. This table is based on the calculation of standard specification execution mechanisms. If the maximum working pressure difference exceeds the range listed in the table, it can be reported to the manufacturer and appropriate solutions can be taken.
2. This table is based on the calculation of valve closing position. Therefore, there will be greater allowable pressure differences in other locations.
