1.Fluid resistance is small, and the coefficient of resistance is equal to that of the same length.

2.Simple structure, small size and light weight.

3.Close and reliable, ball valve sealing surface material widely used plastic, sealing well, in the vacuum system has also been widely used.

4.Easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5.Easy maintenance, valve structure is simple, the sealing ring is generally active, demolition and replacement are more convenient.

6.In the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through, will not cause the valve sealing surface erosion.

7.Suitable for a wide range of sizes from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied


 Water,gas,oil product,natural gas and corrosive mediums as acids,alkalis,etc.
