Air Torque Pneumatic Actuator AT045U-S6-A F03-N-9D – 90° Rotation

Product Description

Air Torque Pneumatic Actuator AT045U-S6-A F03-N-9D – Spring-Return, Rack & Pinion, 90° Rotation, Anodised Aluminium, SIL?3

The Air Torque AT045U-S6-A F03-N-9D is a precision-engineered spring-return pneumatic actuator designed for safety-critical quarter-turn valve automation. Built with a durable rack & pinion mechanism and housed in hard-anodised aluminium, this actuator delivers reliable 90° motion and resilient performance in harsh industrial environments. Fully SIL?3 certified, it is ideal for integration in functional safety systems where fail-safe valve positioning is essential.

Key Features

• Fail-Safe (S6 Spring-Return Sphere): Returns valve to safe position upon losing supply air.

• Consistent Torque Delivery: Rack & pinion drive ensures predictable actuation throughout travel.

• Valve Interface Standard: ISO 5211 F03 flange with 9?mm square (N-9D) shaft drive for broad compatibility.

• Anodised Aluminium Housing: Offers corrosion resistance and robust durability.

• Safety Certification: SIL?3–rated for use in safety-instrumented loops.

• Stroke Control: ±5° external stops for precision end-of-travel adjustment.

• Accessory-Ready Interface: Supports Namur VDI/VDE 3845 standards for solenoids, positioners, and limit-switch mounting.
