Pneumatic unloading ball valve in the pipeline is mainly used to cut off fast, distribution and change the flow direction of the medium. Pneumatic ball valve is widely used in recent years, a new type of valve, which has the following advantages: 1. Pneumatic unloading ball valve fluid resistance is small, the resistance coefficient and the same length of the pipe section. 2. Pneumatic unloading gray ball valve structure is simple, small size, light weight. 3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used. 4. Pneumatic unloading ball valve easy to operate, open and close quickly, from full to complete turn as long as 90 °, easy to remote control. 5. Easy maintenance, pneumatic valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface. 7. Pneumatic unloading ball valve wide range of applications, diameter from a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. Pneumatic unloading ball valve has been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
