Air Torque Pneumatic Actuator AT301U-S10-A F07/F10-N-22DS – 90° Rotation

Product Description

Air Torque Pneumatic Actuator AT301U-S10-A F07/F10-N-22DS – Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3 (Spring-Return)

The Air Torque AT301U-S10-A F07/F10-N-22DS is a safety-oriented spring-return pneumatic actuator designed for reliable quarter-turn valve automation in industrial and process control applications. It features a rugged rack & pinion drive system that delivers smooth and consistent 90° rotation, powered by compressed air, with a built-in return spring for fail-safe operation. The hard-anodised aluminium housing ensures long life and resistance to harsh environments. Fully SIL?3 certified, this actuator meets functional safety requirements for critical control loops.

Key Features

• Fail-Safe Operation (S10 Spring-Return): Automatically returns the valve to its default position if air pressure is lost.

• High Torque Consistency: Rack & pinion mechanism provides uniform torque throughout the stroke.

• Wide Valve Compatibility: Supports ISO 5211 F07 and F10 flange mounts with 22?mm square (DS22) drive shaft, suited for medium to large valve interfaces.

• Robust Construction: Anodised aluminium body withstands corrosion and mechanical wear.

• Safety Certified: SIL?3 compliant for use in safety-instrumented systems.

• Precision Stroke Control: External ±5° travel stops allow fine adjustment of end-positions.

• Accessory Interface: Namur VDI/VDE?3845 standard mounting for solenoids, switchboxes, and positioners.
