Position indicator with NAMUR is convenient for mounting accessories such as Limit Switch box, positioner and so on.
Thepinion 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 body can be treated with hard anodized, powder polyester painted ( different
Colors are available such as blue, orange, yellow etc. ), PTFE or Nickel plated.
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
Made from low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.
NBR rubber O-rings provide trouble-free operation at standard temperature ranges. For high andlow temperature applications Viton or Silicone.
► Pneumatic Valve Actuator
Spring return actuators
1. Pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.
2. 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.
3. 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.
4. 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.
VS series pneumatic actuators (rack& pinion) have the following features.
> 15 actuator models, the output torque from 9NM to 4620Nm at 6 bar air supply.
