What is a double eccentric butterfly valve
Double eccentric butterfly valve is also called high-performance butterfly valve. It is mainly used for drainage of water plants, power plants, steel smelting, chemical industry, water source engineering, environmental facility construction, etc. It is especially suitable for water pipelines as regulating and intercepting equipment. Compared with the centerline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, has a longer life and good stability. Compared with other valves, the larger the diameter, the lighter the material, and the lower the cost. But because there is a butterfly plate in the middle, the flow resistance is large, so a butterfly valve smaller than DN200 is meaningless.
