China Aw Series Pneumatic Actuator for Big Size Butterfly Valve or Ball Valve

Main features:
•AW pneumatic actuator is divided into double-acting and single-acting (spring return), with two separate cylinders, large output torque and flexible balance.
• The inner wall of the cylinder and the piston shaft are plated with hard chromium, which has good wear resistance.
• All sliding parts are equipped with oil-free lubrication shafts and guide rings to reduce friction coefficient and extend service life.
•AW pneumatic actuator U curve characteristic output torque is more suitable for large diameter ball valves and butterfly valves.
• Rotation Angle: 90°±5°
• Use clean air as medium, high safety factor.
• Basic design: pneumatic double cylinder and double piston fork drive mechanism.
• Accessory functions: it can be equipped with single (double) electric solenoid valve, limit switch, air treatment FRL and manual operating mechanism, fully realizing automatic or manual control.
• use clean air as medium, high safety factor.
• accessory functions: it can be equipped with single (double) electric solenoid valve, limit switch, air source processing triplet and manual operating mechanism, fully realizing automatic or manual control.
