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.
