1, opening and closing without friction. This function completely solves the problem that traditional valves affect the sealing due to mutual friction between the sealing surfaces. 2, the body structure. Valves installed in the pipeline can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs. 3, single seat design. Elimination of the valve cavity medium due to abnormal pressure and affect the use of safety issues. 4, low torque design. Special structure design of the valve stem, just with a small handle valve can easily open and close. 5, wedge seal structure. Valves rely on the mechanical force provided by the valve stem, the ball wedge pressed to the seat on the seal, so that the valve seal from the impact of pressure changes in the pipeline under various conditions, the sealing performance has a reliable guarantee. 6, self-cleaning sealing surface structure. When the ball is away from the valve seat, the fluid in the pipeline passes through the sealing surface of the ball evenly, which not only eliminates the local erosion of the valve seat by the high-speed fluid, but also rushes away the accumulations on the sealing surface to achieve the purpose of self-cleaning .
