Not All Ball Valves Are Called 2 Piece Threaded Ball Valve

2 Piece Threaded Ball Valve in a hard-seal ball valve is typically treated using advanced spray technology and various conditions, achieving a maximum hardness of HRC 78. The seat surface of a hard-seal ball valve can achieve a maximum hardness of HRC 72 after treatment. To ensure a perfect fit between the ball and seat, the entire sealing surface of the ball valve is precision ground.

The metal seat ring of a hard-seal ball valve contacts the ball surface, and the spring load acting on the seat ring creates a seal between the two surfaces.

Hard-seal ball valves are suitable for high-temperature, high-pressure water, steam, petroleum, and viscous and corrosive media. Metal-seal ball valves are available in both floating and fixed ball configurations.

Working Principle of Hard-seal Ball Valve:

Hard-seal ball valves, manual cast steel hard-seal ball valves, utilize advanced spray technology to treat the body surface for various operating conditions, achieving a maximum hardness of HRC 78. The seat sealing surface is treated to a maximum hardness of HRC 72. The ball and seat are ground together, and all sealing areas of the entire ball valve sealing surface are precision ground. Suitable for high-temperature, high-pressure water, steam, oil, coal, fiber, viscous and corrosive media, and media containing particles. Metal-sealed ball valves are available in floating and fixed ball configurations. The metal seat ring contacts the ball surface, and a uniform spring load acts on the seat ring to create a seal between the seat ring and the ball.
