Double Offset Butterfly Valve


The double offset butterfly valve is gradually improved by the ordinary butterfly valve that adapt to different working conditions. This type of butterfly valve seal consists of metal-rubber, which is sealed by a small compression of the rubber on the metal seat to create a seal.

The double offset effect allows the disc to be quickly disengaged from the valve seat after the valve is opened, which greatly eliminates unnecessary over-squeezing and scraping of the disc and the valve seat, reduces the opening resistance, reduces wear and improves the seat life. The scraping is greatly reduced, and the double offset butterfly valves can also be used with a metal valve seat, which improves the application of the butterfly valve in the high temperature field.
