　　Stainless steel pneumatic ball valve products overview

　　The working principle of pneumatic stainless steel ball valve is love by rotary valve to keep the valve open or closed. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as in People's Daily life.

　　Stainless steel pneumatic ball valve features

　　1. The fluid resistance is small, its resistance coefficient with section of equal length.

　　2. Simple structure, small volume, light weight.

　　3. 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.

　　4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

　　5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.

　　6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.

　　7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
