3-Position Pneumatic Actuator
By Aira Euro Automation

Aira Euro Automation introduces a versatile 3-Position Pneumatic Rotary Actuator, designed for enhanced control and flexibility in various industrial applications. This actuator enables positioning at 0°, 45°, 90°, or any field-adjustable intermediate angle—achieved through a unique mechanical brake system powered by two auxiliary pistons. It operates using double-acting actuation, ensuring smooth transitions between positions with 100% repeatability.

Engineered for precision tasks such as coarse-fine adjustments in batching or liquid filling systems, the actuator offers mechanical reliability, operational consistency, and precise control through field-adjustable intermediate stops.

  • Cycle Life: Up to 500,000 cycles (POD Certified)
Features & Benefits
3-Position Control:
Offers 0°, 45°, 90° or custom mid-position for accurate process control.

Ideal for Batching Systems:
Perfect for coarse-fine adjustments in batching operations or liquid filling systems.

Double Acting Design:
Ensures consistent actuation with air pressure in both directions for precise positioning.

Mechanical Stopping System:
Auxiliary pistons and mechanical stoppers allow exact intermediate positioning with full repeatability.

Solenoid-Controlled Positioning:
Seamless switching between any two positions via solenoid valves for flexible automation control.

Field Adjustable Intermediate Stop:
Default mid-position at 20% opening; can be easily tuned via set screw for custom requirements.

Reverse Action as Standard:
Inward piston stroke opens the valve, outward stroke closes—opposite to standard actuator configurations.

Adjustable End Stops:
Fine-tune valve closing/opening angles using +/-10° adjustable end stops on both sides.

Long Operational Life:
Engineered for high-performance, long-term reliability with a life span of up to 500,000 cycles.
