AW pneumatic actuator
詳情介紹
The product description
Main features:
AW pneumatic actuator is divided into double-acting type and single-acting type (spring return), two separate cylinder, easy to manufacture large-size cylinder, large output torque, flexible and stable action; 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 shaft and guide ring to reduce the friction coefficient and extend the service life. AW pneumatic actuator's u-shaped curve characteristic output torque is more suitable for large-caliber ball valves and butterfly valves.
Standard parameters:
| basic design | Pneumatic double-cylinder double-piston fork drive mechanism; Model AWxx= double acting type; Model AWxxS= single acting (spring return). |
