Ball valve is mainly used to cut off and connect media in piping, can be used for fluid regulation and control. The main features of valve is compact structure, reliable sealing, simple, easy maintenance, sealing surface and spherical often stay in closed state, anti scour, easy operation and maintenance,apply for water, solvents, acids and natural gas in general working medium in all sectors.
Advantages:
1.Small fluid resistance, the whole diameter of the ball basically has no flow resistance.
2. Simple structure, small and light.
3. Tight and reliable. It has two sealing surface, sealing surface material is widely used in a variety of plastic at present, sealing well, can be completely sealed. Has also been widely used in the vacuum system.
4. Easy to operate, open and shut rapidly, from fully open to fully closed as long as rotate 90 °, to facilitate remote control.
5.Easy maintenance,simple, seal ring is general movable, easy to dismantle and replace.
6. Sealing surface of ball and valve seat is separate with media when full open and full closed, this will not cause the erosion of sealing surface when medium pass.
7. Wide application,the range of nominal diameter is froma few millimeters to a few meters from the high vacuum to high pressure.
