ZMAM/ZMBM pneumatic diaphragm sleeve control valve

Pneumatic diaphragm sleeve adjusting valve, is the general product of pneumatic actuators. Control the flow of media according to gas signal.

Structure principle

Made up of pneumatic diaphragm actuator and sleeve valve. Gas signal input into air room of diaphragm, drive putter to move, drive the valve plug components, valve plug move up and down in sleeve, change the flow section, flow of media changes.
