How Double Eccentric Butterfly Valve Works

FONT

May 16,2022

Double Eccentric Butterfly Valve, also known as high-performance butterfly valve, is mainly used for drainage of water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facilities construction, etc. Compared with the centerline butterfly valve, the Double Eccentric Butterfly Valve is more resistant to high pressure, has a longer life, and has better stability.

How Double Eccentric Butterfly Valve works:
The Double Eccentric Butterfly Valve is further improved on the basis of the single eccentric butterfly valve. Its structural feature 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.
