Ball valve is mainly used to disconnect or connect the medium and can also be used to adjust and control the fluid. V type ball valve can carry out the relatively precise adjustment and control of flow volume, while three–way ball valve is used to dispatch the medium and change the flow direction of the medium. Compared with other types of valves, ball valve has the following advantages: The fluid resistance is small, and ball valve is the one which has the smallest fluid resistance among all types of valves, even the fluid resistance of the necking ball valves is quite small. The process of opening and closing is fast and convenient. As long as the valve stem rotates 90 degrees, the ball valve completes the total opening or closing action, which is easy to realize the fast opening and closing.

The structure design of elastic materials has been adopted for floating ball valve sealing ring. However, the structure design of the elastic float valve seat has been adopted for the trunnion mounted ball valve. It can be designed to have the sealing functions, such as fire–proof and anti–static–electricity. Full welding of the ball valve body can be directly in the ground, so that in case the valve from erosion and it is the ideal valve for oil and natural gas pipeline.
