Advantage:

Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve that has been widely used in recent times. It has the following advantages:

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

2. Simple structure, small size and light weight.

3. Tight and reliable, the sealing surface material of the ball valve is widely used plastic, and the sealing performance is good, and it has also been widely used in the vacuum system.

4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. It is easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the entrance and exit to cut off the flow.
