Air Torque AT451U Pneumatic Valve Actuator F10-F12-27DS

Product Description

Air Torque AT451U Pneumatic Valve Actuator F10-F12-27DS 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 F10 F12 ISO 5211 drilling with a 27DS female drive, so it fits a matching valve pad directly.

Part codes: AT451U-D-A (double acting) and AT451U-S10-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.
