(1)Construction
1.Die-cast aluminum (ASTM6005) body, can be treated with anodized, epoxy, PTFE or Nickel plated.  Inner surface fine grinding process, both internal and external use advanced anticorrosion technology, cylinder friction coefficient is small, long service life.
2.Die-cast aluminum end caps can also be treated with PTFE, Nickel plated. 
3.Nickel plated alloy steel or stainless steel output shaft.
4. Rack & pinion design, symmetrical installation position, easy to change the output shaft steering, quick action.
5.Antifriction sliding bearings.
6.Stainless steel fasteners.
7.Fully in line with international standards: NAMUR, ISO5211, DIN3337.
8.Rotation angle : 90° ± 5°.  Pneumatic actuators of different stroke can be customized as required (e.g. 120°, 135°, 180° etc.)


(2)Double acting 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 acting 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.
