Double eccentric butterfly valve
- Feb 03, 2018 -

Double eccentric butterfly valve, also known as high-performance butterfly valve, is mainly used for water drainage in waterworks, power plants, steelworks smelting, chemical industry, water source spring projects, environmental facilities construction and the like, and is especially suitable for use on water pipelines as a regulating and intercepting device. Compared with the midline butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life expectancy and good stability. Compared with other valves, the larger the diameter of the material lighter, the cost is lower. However, due to the middle of the disc, the flow resistance, so less than the DN200 butterfly valve is not of great significance.
