This series of metal sealed ball valves are suitable for high temperature, high pressure and other occasions, and can achieve zero leakage of the valve seat. HVOF equipment is used to spray tungsten carbide or chromium carbide alloy with high hardness on the surface of the ball and valve seat, which has the characteristics of high erosion resistance, high wear resistance and long service life. Dongchen's unique grinding technology is used to completely seal the valve seat and ball valve. Due to the action of the spring, the valve seat is always in contact with the ball surface, and its self-cleaning function is used to prevent foreign matters from entering the sealing surface. Although the structure of this series of ball valves is simple, it is most suitable for  extreme conditions such as slurry and dusty condition. The packing part adopts the structure of dynamic load, which can effectively prevent the leakage of packing.
