When the sphere is tilting away from the valve seat, the fluid in the pipeline along the sphere sealing surface as evenly through 360 °, not only eliminates the high-speed fluid on the seat of local erosion, bu t also washed away the accumulation of material of the sealing surface of the, to achieve the purpose of self-cleaning .
Structural features:
1, open and close without friction. This feature completely solve the traditional [wiki] valve [/ wiki], the mutual friction between the sealing surface to affect the seal.
2, the coat structure. Valve installed on the pipe directly on-line inspection and maintenance, can effectively reduce the plant closings, and reduce costs.
3, single-seat design. Elimination of the valve in the cavity medium due to abnormal pressure and affect the use of safety problems.
4, low-torque design. Special structural design of the stem, just with a small hand valve can open and close easily.
5, wedge-shaped sealing structure. Valve by stem provides the mechanical force, the ball wedge pressure to a seat on and seal, the sealing of the valve from the pipeline pressure changes affect the sealing performance under various conditions have a reliable guarantee.
6, self-cleaning of the sealing surface of the structure. When the sphere is tilting away from the valve seat, the fluid in the pipeline along the sphere sealing surface as evenly through 360 °, not only eliminates the high-speed fluid on the seat of local erosion, but also washed away the accumulation of material of the sealing surface of the, to achieve the purpose of self-cleaning .
