Pneumatic Actuator Construction
1, Indicator
Pneumatic actuator position indicator with NAMUR is convenient for mounting
accessories such as Limit Switch box, positioner and so on.
2, Pinion
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.
4, Endcaps
Pneumatic actuator Die-casting aluminum powder polyester painted in different colors,
PTFE or Nickel plated.
5, Pistons
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.
9, O-rings
NBR rubber O-rings provide trouble-free operation at standard
temperature ranges. For high andlow temperature applications Viton
or Silicone.
