Nickle Plated Quarter Turn Pneumatic Actuator , Rotary Air Actuator Anticorrosive

Rotary Air Actuator Quarter Turn Pneumatic Actuator Air Actuator Double Acting Pneumatic Actuator Nickle Plated

Pneumatic quarter-turn actuators are divided into two categories, including gear rack structure and fork structure, namely BGT series and BAW series. They are actuating device that turn on/off Quarter-turn valves like ball valves, butterfly valves. Among which BAW series can drive high torque valve.

According to users’requirements, devices like solenoid valve, positioners, reply device, filter regulator, limit switches and manually operated devices can be mounted on the pneumatic actuators.

► Construction

1, Indicator

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

2, Pinion

Thepinion 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 colors, PTFE or Nickel plated.

5, Pistons
The twin rack pistons are made form Die-casting aluminum treated with Hard anodized or madeform 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 travelstop adjustment bolts can adjust± 5° At both open and close directions easily and precisely.

7, High-performance springs
Preloaded coating springs are made formth 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 the quantity 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.

9, O-rings
NBR rubber O-rings provide trouble-free operation at standard temperature ranges. Forhighandlow 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.
