Metal Seated Ball Valve
The surface of the manual cast steel metal seated valve body adopts advanced spraying technology. Through the treatment of various working conditions, the maximum hardness can reach HRC78. The maximum hardness of the seat sealing surface can reach HRC72. The ball body and the valve seat are matched and ground, and all the sealing areas of the entire sealing surface of the ball valve are precision ground. Suitable for high temperature and high pressure water, steam, petroleum, coal, fiber, thick and corrosive media, and media with particles. The metal seated ball valve has two structures: floating ball and fixed ball. The metal seat ring is in contact with the spherical surface, and the valve seat ring forms a seal with the spherical surface by the uniform spring load acting on the valve seat ring. Due to the spring load, the auxiliary seal expands to achieve the seal between the valve body and the valve seat. The spring load is sufficient to provide a reliable seal between the valve seat and the ball. Under low pressure conditions, it can be designed between the seat sealing surface and the ball There is a sealing grease injection system.
