Knowing The Working Principle Of 2pc Flanged Ball Valve Will Help You Know How To Improve Efficiency

This 2PC Flanged Ball Valve utilizes advanced spray coating technology to achieve a maximum hardness of HRC 78 through treatment for various operating conditions. The seat sealing surface is treated to a maximum hardness of HRC 72. The ball and seat are ground to a precise finish, and all sealing areas of the entire ball valve are precision-ground. This valve is suitable for high-temperature, high-pressure water, steam, oil, coal, fiber, viscous and corrosive media, and media containing particles. Metal-seated ball valves are available in floating and fixed ball configurations. A metal seat ring contacts the ball surface, and a uniform spring load acts on the seat ring to create a seal.

The spring load causes the auxiliary seal to expand, creating a seal between the valve body and seat. The spring load is sufficient to provide a reliable seal between the seat and ball. Under low-pressure conditions, a sealing grease injection system can be designed between the seat sealing surface and the ball.
