AW pneumatic actuator

详情介绍

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:
