Product Description

The cast steel eccentric half ball valve uses the eccentric valve body, eccentric ball and valve seat. When the valve rod rotates, it will be automatically centered on the common track. During the closing process, it will be tighter and tighter, completely achieving the purpose of good sealing. The ball of the valve is completely separated from the valve seat, eliminating the wear of the sealing ring, overcoming the problem that the traditional ball valve seat and the sealing surface of the ball are always worn. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the valve seat is well protected. This product is especially suitable for steel industry, aluminum industry, fiber, micro solid particles, pulp, coal ash, petroleum gas and other media.
