▋ Characteristics
High Tensile Spring Sets
High tensile epoxy coated spring sets provide high performance in fail safe and emergency shut down operations.
NAMUR Mounting
Direct mounted solenoid connections according to NAMUR standards.
ISO 5211 Bottom Mounting Connection
Base drilling, for valve mounting, and centering, according to ISO 5211/DIN 3337 standards.
High Visibility Position Indicator
The indicator is to remain on the actuator for continuous indication when limit switch is not being used.
▋ Working Principle of Single Acting (Spring Return) Pneumatic Actuator
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.
▋ Working Principle of Double Acting Pneumatic 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.
