1. It has the lowest flow resistance (actually 0).
2. It can be used for corrosive medium.
3.In the larger pressure and temperature range, can achieve complete sealing.
4. Fast opening and closing can be realized, and the opening and closing time of some structures is only 0.05~0.1s.
5. When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.
6. Due to the compact structure and light weight, it can be considered as the most reasonable valve structure for low-temperature medium system.
7. The closing part can withstand the high pressure difference during the closing.
8. The ball valve of all-welded valve body can be buried directly in the ground,The maximum service life can be up to 30 years, which is the most ideal valve for oil and natural gas pipelines.
