Electric Eccentric Ball Valve

The use of eccentric valve body, eccentric ball and valve seat, stem rotation movement in the common trajectory of automatic centering, closing process is tighter, fully achieving good sealing purpose. The ball and seat of the valve are completely separated, eliminating the wear of the sealing ring, overcoming the problem of the traditional ball seat and ball sealing surface always wear, non-metallic elastic materials are embedded in the metal seat, and the metal surface of the valve seat is well protected.
