Metal-to-metal sealing, anti-thermal expansion and fire-safe design. Specially engineered for high temperature, high pressure, heavily corrosive and particle-laden media, suitable for extreme operating conditions in petroleum, chemical, gas, power generation and other industrial sectors.

This ball valve adopts a floating ball design with a three-stage sealing structure. When the valve is closed, medium pressure pushes the ball tightly against the outlet-side valve seat, forming a dynamic self-sealing seal to achieve zero leakage.
