Metal hard-sealed floating ball valve
Get In Touch →Main Features
The metal hard-sealed ball valve manufactured by our company adopts an elastic metal seat structure with automatic compensation function. Under normal closing conditions, it ensures contact between the ball sealing surface and the seat sealing surface. Under high-temperature working conditions, it can effectively compensate for the thermal expansion of internal parts and prevent jamming caused by high temperatures. The ball surface undergoes special hardening treatment, while the entire seat is made of special hard material or locally overlaid with hard alloy material to ensure a proper hardness difference between sealing pairs. It operates flexibly under high-temperature conditions, and its sealing surfaces are resistant to scratching. It is especially suitable for high-temperature media containing various dust and solid particles.
