    working principle

    Pneumatic actuator working principle:
    Double acting

    Double acting working

    (Counterclockwise)
    Compressed air to Port 2 forces the pistons outwards, causing the output shaft to turn counterclockwise, while the air is being exhausted from Port 4.(Clockwise) Air to Port 4 forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port 2.

    Single actingSingle acting working

    (Clockwise)
    Loss of air pressure, the stored energy in the springs forces the pistons inwards,the pinion turns clockwise, while air is being exhausted from Port 4.
