double acting or single acting aluminum alloy 90 degreepneumatic rotary actuator
Pneumatic Actuator Construction
Pneumatic actuator position indicator with NAMUR is convenient for mounting accessories such as Limit Switch box, positioner and so on.
Pneumatic actuator pinion is high-precision and integrative, made form nickelled-alloy steel, fully conform to the latest standards of ISO5211, DIN3337, NAMUR. The dimensions can be customized and the stainless steel is available.
3, Actuator Body
According to the different requirements, the extruded aluminum alloy ASTM6005.The actuator body can be treated with hard anodized, powder polyester painted ( different colors are available such as blue, orange, yellow etc. ), PTFE or Nickel plated.
Pneumatic actuator Die-casting aluminum powder polyester painted in different colors, PTFE or Nickel plated.
The twin rack pistons are made form Die-casting aluminum treated with Hard anodized or made form Cast steel with galvanization. Symmetric mounting position, long cycle life, and fast operation, reversing rotation by simply inverting the pistons.
6, Travel adjustment
The tow independent externaltravelstop adjustment bolts can adjust± 5° At both open and close directions easily and precisely.
7, High-performance springs
Preloaded coating springs are made form the High-performance trial for resistant to corrosion and longer service life, which can be denounced safely and conveniently to satisfy different requirements of torque by changing thequantity of springs.
8, Bearings & Guides
Aluminum Alloy Rack Pinion Pneumatic Actuator Air Quarter Turn Actuator ISO5211/DIN3337 made from low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.
