Double Acting Spring Return Pneumatic Actuator Rack And Pinion AT Series Customized Design

Pneumatic Actuator Rack And Pinion AT Series double acting spring return

Pneumatic actuator

Rack and Pinion actuators are intended for the automation and operation of quarter-turn valves like butterfly valve,ball valve and plug valves. The dual, opposed rack pistons have low friction bearings and guides that provide high-performance, long cycle-life, and fast response. These pistons can be inverted to reverse the rotation for fail open applications.

Double acting pneumatic actuators
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.

Spring return pneumatic actuators
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.
