Advantages of fully welded ball valve
As ball valves fully welded, there will no external leakage . And the seat is composed of carbide teflon sealing ring and spring which has strong ability of adapting to changes in pressure and temperature for a leak free operation. Processing of ball was detected and tracked by advanced computer detector, so the ball has been precision machining . Because valve body material is the same as pipe material, unevenness or deformation will not occur even when earthquakes happened or heavy cars run along, pipeline is endurable to aging. Seal ring material is PTFE which guarantees no leaks .
