Double offset butterfly valve

Double eccentric butterfly valve is also called high performance butterfly valve, which is mainly used in water plant, power plant, steel smelting, chemical industry, water source engineering, environmental facilities construction and other systems for drainage, especially for waterway pipeline, as a regulating and intercepting device. Compared with the midline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, longer life, and good stability.
