NAUMR Standard Double Acting Rack and Pinion Pneumatic Actuator
► Specifications of Pneumatic Actuator
1. Acting type: Double
2. Medium: clean, dry and without corrosive compressed air
3. Air supply pressure: 0.25 -0.8 Mpa
4. Working Temperature: Standard Type: -20°C~+80°C
Low-temperature Type: -40°C~+80°C
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.

► Design & Construction Of AT Series Double Acting Pneumatic Actuator
1. Full conformance to the latest specification: ISO5211DIN3337VD/VDE3845and NAMUR.
2. The extruding high-intensity aluminum body possesses a honed internal surface coated with hone anode oxygenation for long life, low coefficient of friction and swift performance.
3. Excellent, compact and modernized construction along with multi-specifications make the selection both economic and beneficial.
4. All acting surfaces adopt high-quality bearings, resulting in low friction, high cycle life, and no noise. The two independent external travel stop adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
5. The same outline actuator has the functional modes of double acting and spring return, and the spring return has the normal-open and normal-close styles.
6. Multi-function position indicator with NUMER is convenient for mounting accessories.
7. Pre-compressed load spring is convenient for safe mounting and teardown procedures.
8. Die-casting aluminum pistons and end caps have high intensity and lightweight.
9. Different O-rings materials are available for high and low temperature.
10. According to different demands we can offer Multi-travel rotations (e.g. 120°135°180°) and three position actuators.
11. Solenoid valves are easily mounted without any connecting plank.
