1. The fluid resistance is small, the whole diameter ball valve has no flow resistance basically.
2. Simple structure, small size, light weight.
3. Close and reliable. It has two sealing surface, and the ball valve sealing surface materials widely used all kinds of plastic, good sealing, can achieve complete sealing. Also widely used in vacuum systems.
4. Easy to operate, open and close quickly, from full open to all closed as long as the rotation of 90 °, easy to control the distance.
5. Easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully or completely closed, the ball and valve seat sealing surface and media isolation, media through, will not cause valve seal surface erosion.
7. Wide application range, ranging from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied.
8. As the ball valve in the opening and closing process has a clean, so it can be used in the media with suspended solids particles.
