【Performance Specification:

The Bronze Butterfly Valve is designed so that the stem and disc concentricity are on the same line and perpendicular to the valve body. The valve body adopts a split type, and the sealing at both ends of the valve shaft is controlled by the fluorine-based rubber on the rotating base between the valve disc and the valve seat to ensure that the valve shaft does not contact the fluid medium in the pipeline. 

Copper alloy valves are especially suitable for medium seawater and brine, and are usually used for medium and low pressures.
