Air Torque Pneumatic Actuator AT501U-S10-A F10/F12-N-27DS – 90° Rotation

Product Description

Air Torque Pneumatic Actuator AT501U-S10-A F10/F12-N-27DS – Rack & Pinion, 90° Spring-Return, Anodised?Aluminium, SIL?3

The Air Torque AT501U-S10-A F10/F12-N-27DS is a rugged spring-return pneumatic actuator tailored for fail-safe quarter-turn valve automation in industrial systems. Featuring a sturdy rack & pinion mechanism, this actuator delivers smooth 90° rotation, and its built-in spring ensures a default valve position on air loss. With a hard-anodised aluminium housing, it combines light weight with corrosion resistance and structural durability. Supporting ISO 5211 F10 or F12 flange configurations and a 27?mm square DS27 drive shaft, the actuator offers maximum compatibility. Fully SIL?3 certified, it’s ideal for integration into functional safety systems.

Key Features

• Spring-Return Mechanism (S10): Provides automatic fail-safe positioning when air pressure fails.

• Precise Torque Delivery: Rack & pinion drive maintains consistent force across the stroke.

• Wide Valve Compatibility: Works with ISO F10 or F12 flange patterns and DS27 (27?mm square) drive shaft.

• Corrosion-Resistant Construction: Hard-anodised aluminium body ensures longevity in harsh environments.

• SIL?3 Certified: Compliant with high-integrity functional safety requirements.

• Stroke Adjustment: External ±5° travel stops for fine-tuning the end-of-stroke positions.

• Accessory-Ready Interface: Built-in Namur (VDI/VDE?3845) port for mounting solenoids, positioners, or limit switches.
