Product Features:
I produced the metal seal valve elastic metal seat structure with automatic compensation function, under normal circumstances is closed, make sure that the ball sealing surface contact with the valve seat sealing surface; in high temperature conditions, can effectively compensate within pieces of thermal expansion, to avoid high temperature caused by jamming. Sphere surface with special hardened valve seats with special hard material overall or partial surfacing carbide materials, to ensure that there is proper hardness difference between sealing. In the high-temperature conditions hoist flexible, and the sealing surface is not easily scratched. Especially for high temperature and dust and solid particles with a variety of media.
