ZHA/B Type Pneumatic Diaphragm Actuator
ZHA/B type multi-spring pneumatic diaphragm actuator change output pressure of pneumatic adjustment gauge into push rod displacement change. It can connect a straight trip control valve to change the control system output signal into disk corresponding position to realize to control valve open degree. It has force uniform, good stability, large output push, small size, lightweight, and other advantages.
