High performance Spring Return Scotch yoke pneumatic actuator for ball valves

►Construction-Pneumatic Actuator

1. Using technology of plating hard chroming of the cylinder inner wall, it is corrosion resistant and wear resistant, which can ensure longer working life

2. NAMUR standard size, suitable for installation of limit switch, positioner and other accessories

3. Orbit is treated by high frequency quenching and grinding, with knock-down design, low maintenance cost

4. High strength copper alloy, sliding block with graphite self lubricating function, square anti jamming design

5. Spring fixed way, to protect the integrity, safety and service life of components

6. Large square flexible, increasing the life of the overall heavy-duty pneumatic actuator components

7. Special custom alloy steel pin shaft, higher strength and superior wear resistance performance, the strength is 7-8 times higher than normal carbon steel

8. Double travel adjustment bolts, adjustable range is within ±6°

9. Special increased valve shaft bore diameter design, can install thicker diameter shaft directly without coupler and bracket

10. Unique new dual rod guide structure, torque distribution is more reasonable

11. Whole polishing, three bottom three sides with paint treatment, which dramatically improves firmness of the painted surface and overall corrosion resistant performance
