Double eccentric butterfly valve, also known as high performance butterfly valve, is mainly used for water plant, power plant, steel smelting, chemical industry, water source engineering, environmental facilities construction and other systems drainage, especially for water pipeline, as a regulation and closure equipment. Compared with the center line butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life, good stability. The larger the diameter, the lighter the material and the lower the cost compared to other valves. But because there is a butterfly plate in the middle, the flow resistance is large, so less than DN200 butterfly valve is not very significant.
