The feature of our products:
1 They are widely used in petroleum and petrochemical,steel,shipbuilding,energy,electric powder,water treatment,paper making,oil refining,matallurgy,air conditioning,electronics and other industries.
2. The extruded cylinder body is made of high quality aluminum alloy with fine machined socket and hard anodized outer surface( anodisation would be provided at special occasion + coat)to prolong the service life and lower the coefficient of friction.
3. Die-casting aluminum powder polyester painted in different colours,PTFE or Nickel plated.
4. The two independent extemal travel stop adjustment bolts can adjust ±5°at both open and close directions easily and precisely.
5. Made from low friction,long-life compound material,to avoid the direct contact between metals.The maintenance and replacement are easy and convenient.
6. NBR rubber O-rings provide trouble-free operation at standard temperature ranges,for high and low temperature applications Viton or Silicone.
7. Temperature range -20°C to +80°C (-Standard ) ., -35°C~+80°C( Low temperature ), -15°C~+150°C ( High temperature ).
8. Better price and good quality,if you have a trial order ,you will hope a long-time cooperation with us.

► 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.
