Double Flange Double Eccentric Butterfly Valve
The double-eccentric butterfly valve is also called a high-performance butterfly valve, which is mainly applicable to the drainage of water works, power plants, steel works, chemical industry, water source engineering, environmental facility construction and the like, and is especially suitable for the water channel pipeline and is used as an adjusting and intercepting device. Compared with the middle-line butterfly valve, the double-eccentric butterfly valve is more resistant to high pressure, the service life is longer, and the stability is good. Compared with other valves, the larger the caliber, the lighter the material, and the cost is lower. However, because of the butterfly plate in the middle, the flow resistance is large, so the butterfly valve with less than dn200 is not of great significance.
