Hard seal ball valve the surface of the sphere tend to use the advanced coating technology, first passed to deal with a variety of different conditions, the highest hardness is HRC78 can be achieved. Hard sealing ball valve seat cover after dealing with the highest hardness can reach HRC72, sphere and valve seat to match, the ball valve seal area across the seal face so are going through precision grinding. Metal hard seal ball valve seat ring in contact with the sphere, the role of the seat ring on the spring load of the seat ring and spherical form sealing. Hard seal ball valve is suitable for high temperature and high pressure water, steam, oil, viscous and corrosive medium, metal sealed ball valve floating ball and a fixed structure of the two. Hard seal ball valve working principle: hard seal ball valve, manual cast steel hard seal ball valve body surface using the advanced coating technology, through to the various conditions of processing, the highest hardness can reach HRC78. The processing of valve seat sealing surface, the highest hardness can reach HRC72. Sphere and valve seat match grinding ball Industrial Valves the sealing surface of all sealing area after precision grinding. Suitable for high temperature and high pressure water, steam, oil, coal, fiber, viscous and corrosive medium, and the medium with particles. Metal sealing ball valves have a floating ball and a fixed seat ring in contact with the spherical structure of two kinds of metal, by acting on the seat ring spring load evenly to make seat ring and sealing spherical form.
