Features
· Just to install the company’s spring to make double action into single action with the same design dimensions.
· NAMUR (VDE3845) standard interface can connect with a variety of control devices simply.
· Standard size base link is in line with the ISO5211, DIN3337 standard, can be directly linked with the valve.
· Retrofitting the special stand of our company will be able to achieve the freedom of the cylinder opening function.
· Diameter mirror processing and use special hard-oxidation process, reduce the frictional resistance and wear parts effectively, switch to achieve 500,000 times without wear and tear parts, ensure the product service life and output efficiency.
· Single-action cylinder using a spring-type structure to achieve the miniaturization of the cylinder. To use combination of a spring structure and the number of springs can be adjusted to achieve the requirements of a wide range of output torque.
· Reasonable design, the cylinder lightweight. Reduce weight about 30% compared with similar products.

Operating Principle

1. Air to Port 2 forces the pistons outwards, causing the springs to compress, the pinion turns counterclockwise while air is being exhausted from Port 1.
2.In the event of loss of air pressure or power, the stored energy in the springs forces the pistons inwards, causing the pinion turns clockwise
while air is being exhausted from Port 2, and air to Port 1 can accelerate closing the valve.
3. By changing the installation of the direction of piston can make the cylinder air to open or close.
4. Air consumption (L/min)=air volume opening x (air supply(kpa)+101.3)÷101.3 x action cycle times(/min).
