Principles of Single Acting & Double Acting Actuators

Principles of Single Acting & Double Acting Actuators

Principle of Single Acting Actuator (Spring Return)

CCW

Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.

Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A.

Air to port B forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.

Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A.

Principle of Double Acting Actuator

CCW

Air to Port A forces the pistons outwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port B.

Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A.

*NOTE: Make sure that the torque necessary to operate the valve is compatible with the actuator torque (it depens on both actuator type and air supply). Please note that the requested torque depends not only on the valve,but on the working conditions and the safety margins of the plant in question, too.
