Air Torque Pneumatic Actuator AT201U-S10-A F05/F07-N-17DS – 90° Rotation

Product Description

Air Torque Pneumatic Actuator AT201U-S10-A F05/F07-N-17DS – Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3

The Air Torque AT201U-S10-A F05/F07-N-17DS is a meticulously engineered spring-return pneumatic actuator designed for precision and safety in industrial valve applications. Featuring a robust rack & pinion drive mechanism, it delivers smooth and controlled 90° actuation while returning the valve to a safe position upon air loss. Housed in hard-anodised aluminium, it offers high corrosion resistance and reliable durability. Fully SIL?3 certified, this actuator is ideal for use in safety-instrumented setups across sectors like oil & gas, water treatment, chemical, and power generation.

Key Features

• Spring-Return Design (S10): Automatically closes or opens the valve to a preset safe position in case of air supply failure.

• Consistent Torque: Rack & pinion mechanism ensures uniform torque delivery throughout the stroke.

• Valve Interface Compatibility: Fits ISO 5211 F05 or F07 flange and 17?mm square DS17 shaft, making it suitable for medium to large valves.

• Durable Build: Anodised aluminium body for long-lasting performance in harsh environments.

• SIL?3 Compliant: Meets functional safety standards for mission-critical automation.

• Stroke Control: External ±5° travel stops enable precise end-of-travel adjustment.

• Accessory Ready: Namur VDI/VDE?3845 mounting for solenoid valves, limit switches, or positioners.
