Ductile Iron Soft Seal Double Offset Butterfly Valve For Water Pipeline Use
Product introduction:
The double eccentric butterfly valve is further improved on the basis of the single eccentric butterfly valve and is also the most widely used. Its structural feature is that the valve stem axis deviates from both the center of the butterfly plate and the center of the body. The double eccentricity effect allows the butterfly plate to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive compression and scraping between the butterfly plate and the valve seat, reducing the opening resistance distance, reducing wear, and improving the service life of the valve seat. The significant reduction in scraping also allows for the use of metal seats in double eccentric butterfly valves, improving their application in high-temperature fields.
