This kind of concentric butterfly valve is designed that its concentric of stem and disc are in same line and is perpendicular to body bore Concentric. The valve body adopts the split type, and the seal on both ends of the valve shaft is controlled by the fluorine base rubber on the rotating base between the disc and the valve seat, to ensure that the valve shaft does not contact with the fluid medium in the pipeline. Copper alloy valve is special suitable for medium sea water and salt water , normally used in low and middle pressure.
