Upper ball valve pressure loss is small:
1. When fully open, the water loss is zero, the flow channel is completely unimpeded, and the medium will not deposit in the cavity of the valve body;
2. wear resistance: v-shaped opening between the ball crown and the metal seat has shear effect, in the closing process, only at the last moment the ball crown against the seat, do not form friction, and the seat is made of wear-resistant nickel alloy, not easy to be erosion and wear, so it is suitable for containing fiber, small solid particles, pulp, etc.
Upper ball valve is suitable for natural gas pipeline, valve body is integrated, reduce leakage point, easy maintenance, advanced technology, high acceptance pressure, wide range of use. Valve body as a whole, the upper part of the valve cover, seat, ball, sealing ring are loaded from the upper part. Its advantage is to repair and replace the seat, the ball valve from the pipeline, only open the cover, the ball can be lifted out, this underground pipeline, especially the nuclear industry with the ball valve to bring great convenience.
