Open/close ( A sphere) Driven by the valve stem, and around the axis of rotation movement of the valve stem. Use can also be used on regulation and control of fluid, the 'V' ball valve, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium. The working principle of ball valve is 90 degrees of rotation movement, the cock body for a sphere, a round hole or tunnel through its axis. Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Ball valve is suitable to do the most switch, cut-off valve, ball valve but recent development have designed to make it with throttling and control flow, such as V type ball valve. Fluid resistance small, little flow resistance full size of ball valve. Simple structure, small volume, light weight. The compact and reliable. It has two sealing surface, and the widely use of all kinds of plastic ball valve sealing surface of materials, good sealing, can realize completely sealed. Have been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close just rotate it 90 & deg; To facilitate remote control. Convenient maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient. 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 Industrial Valves have to wipe in the process of opening and closing, so can be used to bring in the medium of suspended solid particles. Faults machining accuracy high, expensive, difficult to use in high temperature, such as pipe contains impurities, easily blocked by impurities, lead to valve cannot open our valve is according to the actual situation to find a suitable your ball valve, and avoid disadvantages.
