Thermostability Eccentric Half Ball Valve for particles, ash, fiber medium
Eccentric half ball valve self centering in the common trajectory using the eccentric body, eccentric ball & seat, and stem for rotational movement, the closing process is more and more tight, to fully achieve a good sealing purpose. The ball and the seat are completely separated, eliminating the wear of the sealing ring, and overcoming the wear problem between the traditional ball valve seat and the ball sealing surface, the non-metallic elastic material is embedded in the metal seat, the valve seat metal surface is well protected.
1.Metal seated, safe and washing-out resistance, long life cycle;
2.Sealing self-compensation, good sealing performance does not jam at low and high temperatures;
3.Double eccentric structure, there is little friction between seat and disc, easy to open and close, sealing function with close more tightly;
4.High temperature, low temperature, corrosion resistance;
5.Horizontal mounting manual valve has bi-directional display function, the opening state of the valve can be observed synchronously from the operating surface and side.
Widely used in water supply and drainage, metallurgy, petroleum, chemical industry, electric power, urban construction and other industrial pipelines to cut off, connected medium, especially for the transport of particles, ash, fiber and other medium industrial pipelines, to cut off medium.
