Comprehensive Guide to Electric Butterfly Valves: Principles, Applications, and Advantages
Electric butterfly valves play a crucial role in industrial automation, off...
Hearken double acting pneumatic actuator has efficient output torque and smooth operation in a compact design which suited for the operation of ball valve, butterfly valve etc…the body is made of extruded aluminum and the end caps are die cast. Every hearken actuator is 100% factory pressure tested to ensure the highest quality pneumatic actuator is achieved. Provides valve accessories, including limit switches, positioners, solenoid valves and mounting bracket and coupling.
HPA Double Acting Pneumatic Actuator is prelubricated and tested to a min one million operations. Actuators are available double acting and spring return models. Its meet international ISO5211 standards for easy vale mounting and replacement visual position indicator will monitor the open and closed position.
