Double flange butterfly valve, has flanges welded to its body – one at the upstream end of the valve and the other at the downstream end of the valve. This type of butterfly valve, used to regulation and flow sectioning in water supply facilities, plumbing, irrigation, etc, is the most resilient seated valve design which is usually used for dead-end service, It has low head loss due to a hydrodynamic design of the disc, it is 100% water tight and need no gaskets to be installed.

Double flanged butterfly valve is easier to mount and center, and is also mechanically stronger in construction than lug or wafer design, making it suitable for heavy-duty, large flow-handling scenarios.
