Hard seal ball valve

▲The design of the metal seat of the hard-sealed ball valve
The surface of the ball of the hard-sealed ball valve produced by our company adopts advanced spraying technology. Through the treatment of various working conditions, the highest hardness can be achieved. The valve seat sealing surface is processed to a maximum hardness. The ball and valve seat are paired and ground, and all 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, viscous and corrosive media, as well as media with particles. Metal seal ball valves have two structures: floating ball and fixed ball
The metal seat ring is in contact with the spherical surface, and the uniform spring load acting on the valve seat ring causes the valve seat ring and the spherical surface to form a seal. At the same time, the auxiliary seal expands due to the spring load to achieve sealing 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, especially under low pressure conditions.
According to user needs, a sealing grease injection system can be designed between the valve seat sealing surface and the ball
▲Fire-resistant design
The fire-resistant design of the valve complies with or standards, and the fire-resistant test specifications are equivalent to this Valves are currently widely used in papermaking, crude oil, natural gas, petrochemicals, and various related industries that contain particles and are prone to wear, erosion, and fire.
