Advantages

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

2. Simple structure, small volume and light weight.

3. It is tight and reliable. The sealing surface of the ball valve is widely made of plastic with good sealing performance. It has also been widely used in the vacuum system.

4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.

5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.

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

7. It has a wide range of applications, ranging from small to several millimeters and large to several meters. It can be applied from high vacuum to high pressure. When the ball rotates for 90 degrees, the inlet and outlet shall be spherical, so as to cut off the flow.
