3-Position Pneumatic Actuator – 90° / 180°
Product Overview & Operating Principles
3-Position Pneumatic Actuator
Our 3-Position Pneumatic Actuators are designed for valve automation and industrial applications requiring an accurate intermediate stopping position.
The actuator provides three-position operation with 0°–45°–90° or 0°–90°–180° rotation. The intermediate position is achieved through an external mechanical stop using two auxiliary pistons.
The intermediate position can be easily adjusted by means of the external nuts located on the outside of the end caps. Both Double Acting and Spring Return configurations are available.
Key Applications
- Dosing applications
- Exact filling operations
- Valve automation
- Process control
- Applications requiring an intermediate stop during 90° or 180° rotation
Operating Conditions
- Maximum supply pressure: 8 bar
- Operating pressure: 2.5–8 bar
- Temperature range: -20°C to +80°C
- Other dimensions: Refer to the standard actuator data sheet
- Output torque: Refer to the standard actuator torque table according to the operating pressure and actuator configuration
