Product Overview

The structural feature of the double eccentric butterfly valve is that the valve stem axis deviates from the center of the butterfly plate and from the center of the body. The double eccentric effect allows the butterfly plate to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive compression and scratching between the butterfly plate and the valve seat, reducing the opening distance, lowering wear, and improving the service life of the valve seat. Mainly suitable for water supply and drainage systems in water plants, power plants, steel mills, papermaking, chemical industry, catering, etc., especially suitable for water supply pipelines.

Structural Features

Flanged Double Eccentric Butterfly Valve adopts double eccentric structure, which has the function of sealing the tighter the valve is closed, and the sealing performance is reliable; the sealing sub-materials are stainless steel and nitrile oil-resistant rubber, which has a long service life; the rubber sealing ring can be located on the valve body or the butterfly plate, which is applicable to different characteristics of the medium for the users to choose.


Flanged double eccentric butterfly valve butterfly plate adopts frame structure, high strength, large overflow area, small flow resistance; the whole baking paint, can effectively prevent rust and corrosion and as long as the replacement of the sealing seat sealing material, can be used in different media; double eccentric butterfly valve has a bi-directional sealing function, the installation of the media is not subject to the control of the direction of flow, and not subject to the influence of the location of the space, can be installed in any direction; flanged double eccentric butterfly valve has a unique structure, flexible, labor-saving, convenient operation, and can be used in any direction. The flanged double eccentric butterfly valve has a unique structure, flexible operation, labor-saving, convenient.
