Actreg Pneumatic Actuator ASR4000-F16-F25-DS55 – Rack & Pinion, 90°

The Actreg ASR4000-F16-F25-DS55 is a premium-class, spring-return rack & pinion pneumatic actuator designed for the most demanding industrial valve automation applications. Providing 90° valve actuation with high torque output and safety-rated operation, it ensures robust performance even with oversized quarter-turn valves.

Key Features

• Fail-Safe Operation: Spring-return (ASR series) ensures safe default position in case of pressure loss.

• High Torque Output: Engineered to operate extremely large-diameter valves with precision and reliability.

• Durable Construction: Hard-anodised aluminium housing delivers corrosion and wear resistance for extended life.

• Standard Valve Interface: ISO 5211 flange compatibility (F16 & F25) and DS55 square shaft (55?mm) for broad valve integration.

• Safety Certification: Fully SIL?3 rated, suitable for safety-instrumented control loops.

• Precise Adjustment: ±5° external travel stops for fine control over stroke end points.

• Accessory Interface: Namur VDI/VDE?3845 mount supports solenoid valves, limit switchboxes, and positioners.

Technical Specifications

Recommended Applications

This actuator is optimally suited for:

• Fail-safe actuation of large ball, butterfly, or plug valves in critical process lines.

• Applications requiring SIL?3-rated components, such as oil & gas, power generation, water/wastewater, petrochemical, and industrial automation.

• Valve systems using ISO F16 or F25 mounting and DS55 drive shaft interfaces.
