Air Torque AT051U Pneumatic Valve Actuator F04-11DS

Product Description

Air Torque AT051U Pneumatic Valve Actuator F04-11DS is a rack and pinion pneumatic valve actuator giving 90 degree quarter-turn operation from a compressed air supply. The body is anodised aluminium and the unit is SIL 3 rated.

It mounts to F04 ISO 5211 drilling with a 11DS female drive, so it fits a matching valve pad directly.

Part codes: AT051U-D-A (double acting) and AT051U-S6-A (spring return).

Double acting uses air to drive the actuator both ways. Spring return uses a spring set to take the valve to its fail-safe position on loss of air.
