Product Feature
· Combination of BZH series Pneumatic diaphragm actuator and sleeve control valve。
· This series of pneumatic sleeve control valve's actuators have
small size, light weight, easy installation and maintenance。
· Sleeve valve adopts balanced valve spool structure,
Small axial unbalanced force,Can withstand greater differential pressure.
· Good stability, good sealing performance, small leakage.
· Reliable action, to bear large differential pressure, a small amount of leakage,
Accurate flow characteristics, Wide adjustable range.
· According to user requirements, can be equipped with Positioner, Air filter pressure reducer,
limit switches, hand wheel, the solenoid valve ect.
