What Advantage Ball Valve
In full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.
Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
Because the ball valve have to wipe in the process of opening and closing, so can be used to bring in the medium of suspended solid particles.
High machining precision, expensive and should not be used in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to valve cannot open.
