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.
CW
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.
CW
Air to Port A forces the pistons outwards, causing the pinion to turn clockwise while the air is being exhausted from Port B.
Air to Port B forces the pistons inwards, causing the pinion to turn counterclockwise while the air is being exhausted from Port A.
Air to port B forces the pistons outwards,causing the springs to compress,The pinion turns counterclockwise
springs to compress,The pinion turns counterclockwise while air is being exhausted from port B.
Direct mounted solenoid connections according to NAMUR standards.
Base drilling, for valve mounting, and centering, according to ISO 5211/DIN 3337 standards.
The indicator is to remain on the actuator for continuous indication when limit switch is not being used.
