The detailed information
advantages

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

2. Simple structure, small size and light weight.

3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.

4, easy to operate, open and close quickly, from full open to full off as long as 90 ° rotation, easy to control over long distances.

5, the maintenance is convenient, the ball valve structure is simple, the sealing ring is generally active, and it is convenient to disassemble and replace.

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

7, a wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spheres should appear at the entrance and exit, thus cutting off the flow.
