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.
