Overview:

Pneumatic ball valve A new type of valve, mainly used in the pipeline to do cutting speed, distribution and change the direction of the media flow.

Pneumatic ball valve only need to use pneumatic actuators with air source rotation 90 degrees of operation and a small torque can be closed tightly. The fully equal body cavity provides a very small, straight passage for the medium. It is generally considered that the ball valve is most suitable for opening and closing. The main features of the ball valve itself is compact, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be the whole, it can be modular.

Pneumatic ball valve works by rotating the valve plug to make the valve open or closed. Pneumatic ball valve switch light, small size, can be made into a large caliber, sealed and reliable, simple structure, easy maintenance, sealing surface and the ball is often closed state, not easily eroded by the media, in various industries have been widely used.
Pneumatic ball valve and plug valve is the same type of valve, only its closure is a sphere, the ball around the center of the body for rotation to achieve the opening, closing a valve.

Advantages:

1. The fluid resistance is small and the drag coefficient is equal to the pipe length of the same length.
2. Simple structure, small size, light weight.
3. Close and reliable, ball valve sealing surface material widely used plastic, good sealing, in the vacuum system has also been widely used.
4. Easy to operate, open and close quickly, from full open to full clearance as long as the rotation 90 °, easy to remote control.
5. Easy maintenance, pneumatic ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.
6. When fully open or fully closed, the ball and the valve seat sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion.
7. Applicable to a wide range of diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
8. Because the pneumatic ball valve power source is a gas, usually 0.2-0.8MPa pressure, relatively safe. Pneumatic ball valve if the leakage, then the relative hydraulic, electric, the gas can be discharged directly, no pollution to the environment, but also has a high security.
9. Pneumatic ball valves can be arranged in large diameter relative to manual and turbo-operated ball valves (manual and turbine-operated ball valves are generally below DN300 and pneumatic valves can reach DN1200 caliber.)
Pneumatic ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily life.
