Double Eccentric Butterfly Valve, Carbon Steel, Features, Supplier

The structural feature of the double eccentric butterfly valve is that the shaft center of the valve stem deviates from the center of the disc and the center of the body. 

The effect of double eccentricity enables the disc to break away from the valve seat immediately after the valve is opened, which greatly eliminates unnecessary excessive extrusion and scratching between the disc and the valve seat, reduces the opening resistance, reduces wear, and improves the Seat life.

The scraping is greatly reduced, and at the same time, the double eccentric butterfly valve can also use a metal valve seat, which improves the application of the butterfly valve in the high temperature field.
