This series of metal sealed ball valves is suitable for various occasions such as high temperature and high pressure, and can achieve zero leakage of the valve seat. Using HVOF equipment, tungsten carbide or chromium carbide alloy with extremely high hardness is sprayed onto the surface of the ball and valve seat, which has the characteristics of high erosion resistance, high wear resistance, and long service life. By utilizing Dongchen's unique research technology, the valve seat and ball valve are completely sealed. Due to the action of the spring, the valve seat is always in contact with the ball surface, using its self-cleaning function to prevent foreign objects from entering the sealing surface. Although this series of ball valves has a simple structure, they are most suitable for harsh conditions such as slurry and dust. The filling part adopts a dynamic load structure, which can effectively prevent the leakage of the filling.
