Product Description

Air Cylinder Spring return Valve pneumatic actuators for big torque

 

 

 

► Construction


1, Indicator

Position indicator with NAMUR is convenient for mounting accessories such as Limit Switch box, positioner and so on.

2, Pinion

The pinion is high-precision and integrative, made form nickelled-alloy steel, full 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 Body can be treated with hard anodized, powder polyester painted ( different Colours is available such as blue, orange, yellow etc. ), PTFE or Nickel plated.

4, End caps
Die-casting aluminum powder polyester painted in different colours, 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 external travel stop 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 quality material for resistant to corrosion and longer service life, which can be denounced safelyand conveniently to satisfy different requirements of torque by changing quantity of springs.

8, Bearings & Guides
Made form 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 and low 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.
