API Double Offset Butterfly Valve Flanged Type
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.The double eccentric effect enables the butterfly plate to detach from 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.The greatly reduced scraping also enables double eccentric butterfly valves to use metal seats, improving the application of butterfly valves in the high temperature field.
