Pneumatic ball valve in the pipeline

Pneumatic ball valve in the line is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control. Convenient maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient. In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
