Air Torque Pneumatic Actuator AT351U-D-A F07/F10-N-22DS – 90° Rotation

Air Torque Pneumatic Actuator AT351U-D-A F07/F10-N-22DS – Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3

The Air Torque AT351U-D-A F07/F10-N-22DS is a durable and reliable double-acting pneumatic actuator, engineered for accurate quarter-turn valve automation. Featuring a precise rack & pinion drive that delivers smooth 90° actuation, it is constructed with hard-anodised aluminium housing to ensure corrosion resistance and longevity in industrial settings. Compatible with ISO 5211 F07 or F10 flange patterns and a 22?mm square (DS22) drive shaft, this actuator integrates seamlessly with medium to large quarter-turn valves. Fully SIL?3 certified, it is ideally suited for safety-instrumented control systems where dependable performance and torque consistency are critical.
