Air Torque Pneumatic Actuator AT701U-S10-A F16-N-46DS – 90° Rotation

Air Torque Pneumatic Actuator AT701U-S10-A F16-N-46DS – Rack & Pinion, 90° Spring-Return, Anodised Aluminium, SIL?3

The Air Torque AT701U-S10-A F16-N-46DS is a heavy-duty spring-return pneumatic actuator engineered to provide reliable, fail-safe quarter-turn valve automation in industrial environments. Featuring a rugged rack & pinion drive system, it delivers smooth 90° rotation with a built-in spring return mechanism. Encased in hard-anodised aluminium, it offers outstanding resistance to corrosion and mechanical wear. Compatible with ISO 5211 F16 flange mount and a 46?mm square (DS46) drive shaft, this actuator fits large valve assemblies. Fully SIL?3 certified, it's designed for integration into safety-instrumented systems.
