Air Torque Pneumatic Actuator AT101U-S10-A F04/F07-N-11DS – 90° Rotation

Product Description

Air Torque Pneumatic Actuator AT101U-S10-A F04/F07-N-11DS – Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3

The Air Torque AT101U-S10-A F04/F07-N-11DS is a high-quality spring-return pneumatic actuator engineered for safe, precise quarter-turn valve operation in industrial settings. Featuring a robust rack & pinion drive mechanism, it delivers controlled 90° actuation, with fail-safe spring return on air loss. Mine-built with hard-anodised aluminium housing, this actuator offers excellent durability and corrosion resistance. Fully SIL?3 certified, it meets stringent safety requirements for functional safety systems.

Key Features

• Spring-Return Mechanism (S10): Ensures fail-safe valve travel in the absence of air pressure.

• Reliable Torque Delivery: Rack & pinion drive offers consistent actuation throughout the entire stroke.

• Flexible Valve Mounting: ISO 5211 F04 or F07 flange compatible with 11?mm square (DS11) shaft interface.

• Durable Construction: Anodised aluminium housing resists wear and corrosion under rugged conditions.

• Safety Certified: SIL?3 rating for integration into critical safety-instrumented loops.

• Travel Stops: External ±5° adjustable stops for precise valve stroke limitation.

• Accessory Ready: Built with Namur VDI/VDE?3845 interface for solenoids, limit switches, and positioners.
