Sleeve Type Control Valve

ZHM Type Sleeve Type Control Valve

ZHM single level sleeve type control valve with high stability, easy maintenance and wide application. It can be designed as balance type for eliminate static unbalance, with damping effect, reduce valve vibration, can be applied in occasion with large pressure difference, can apply with multi-spring pneumatic diaphragm actuator or electric actuator, etc.
