Ball valve is a new type of valve widely used in recent years. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.

2. Simple structure, small volume and light weight.

3. Tight and reliable. At present, plastic is widely used as sealing surface material of ball valve, which has good sealing performance and has been widely used in vacuum system.

4. Convenient operation, fast opening and closing, from full opening to full closing as long as 90 ° rotation, convenient for remote control.

5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement.

6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface.

7. Wide range of application, diameter from small to several millimeters, to several meters, from high vacuum to high pressure can be applied. This kind of valve should be installed horizontally in the pipeline.
