ZJHM Compact Pneumatic Sleeve Control Valve
The ZJHM compact pneumatic sleeve control valve consists of a pneumatic multi-spring diaphragm actuator and a low-flow-resistance sleeve regulating mechanism. Compared with ordinary sleeve valves, it features a 1/3 smaller volume, a 1/3 lighter weight, and a 1/3 larger flow rate. It is widely used in industrial process automatic control that requires low noise and large pressure difference.
