1: The eccentric semi-ball valve adopts an eccentric valve body, an eccentric ball and a valve seat. When the valve stem rotates, it is automatically centered on the same track, and the valve closes more tightly during the closing process, completely achieving a good sealing purpose. The ball and seat of Gui Long valve are completely separated, which eliminates the wear of sealing ring and overcomes the problem that the seat and ball sealing surface of traditional ball valve are always worn. The metal seat is embedded with nonmetallic elastic materials, and the metal surface of the valve seat is well protected. This product is especially suitable for iron and steel industry, aluminum industry, fiber, tiny solid particles, paper pulp, coal ash, liquefied petroleum gas and other media.
