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

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

The Air Torque AT701U-D-A F16-N-46DS is a high-capacity double-acting pneumatic actuator optimized for powerful, precise quarter-turn valve operation. Driven by a robust rack & pinion mechanism, it delivers dependable 90° motion and is built with a hard-anodised aluminium housing for superior resistance to corrosion and mechanical wear. Compatible with ISO 5211 F16 flange mounting and a 46?mm square DS46 drive shaft, it’s engineered to fit larger valve systems. Fully SIL?3 certified, it’s ideal for safety-instrumented loops in critical processing environments.
