ZJHM Compact Pneumatic Sleeve Control Valve

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.

Note:
  1. P—Valve positioner, R—Pressure relay.
  2. The allowable pressure difference is under the condition that the valve is closed and P2=0, and △P is the maximum value.
  3. If the maximum pressure difference exceeds 1.0MPa, the surfaces of the valve plug and sleeve shall be surfacing with cemented carbide.
