Aira Euro Automation offers a 3 position Pneumatic Rotary Actuator. It provides an operation of 0°, 45°, 90°, or the random travel of the middle position. The middle position is achieved by the mechanical brake. That is caused by the movement of the two auxiliary pistons. This actuator comes with double acting actuation. This three position actuator is suitable for coarse-fine adjustment, typically for batching operations or processes. The repeatability is 100% since stopping is by mechanical stoppers. It is suitable for calling for precise fine-coarse adjustment like a liquid filling system.

3 position pneumatic rotary actuator

The actuator can be switched to one position from any other position very easily with the solenoid control. The third position is achieved by the mechanical stopping of the piston movement, in return stroke by pneumatic stopper pistons. The intermediate position is present at 20% opening. The opening can be adjusted as required by the set screw. This is field adjustable.

The actuator as a standard, works in reverse action, as opposed to conventional configuration i.e. piston inward stroke opens the valve, and piston outward stroke closes the valve. The end stops (-/+10°) are provided on the closing and opening sides of the actuator for setting valve closing precisely.
