Product Identification:

Double eccentric butterfly valve is further improved on the basis of single eccentric butterfly valve.The structure is characterized by that the valve stem axis deviates from both the disc center and the body center.Double eccentric effect enables the butterfly plate to leave the seat immediately after the valve is opened, greatly eliminating unnecessary excessive squeezing and scraping between the butterfly plate and the seat, reducing the opening resistance distance, reducing wear and increasing the life of the seat.

Double eccentric butterfly valve is mainly used in water works, power plants, steel smelting, chemical engineering, water source engineering, environmental facilities construction and other systems for drainage.Compared with the center line butterfly valve, double eccentric butterfly valve is more resistant to high pressure, longer life and better stability.
