1. Simple structure, small volume, light weight.

2. Compact and reliable. It has two seal face, and widely used all kinds of plastic ball valve
    sealing surface of materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system.

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

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

5. Good anticorrosive property,the valve sealing surface erosionIn the fully open or fully closed,
the ball and seat sealing surface and the dielectric isolation, medium through, can not cause.

6.Wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied
