Intervalve DXR double flanged range of valves are double eccentric design butterfly valves. These are available in cast as well as fully fabricated design. The face to face dimensions can be either as per BS (Series BC & BF) or as AWWA (Series AC & AF).

These valves incorporate a double offset disc design, which practically eliminates any seat wear. The fully replaceable seat provided on the disc periphery is field replaceable and is capable of achieving bi-directional sealing. The rubber seat seals against a St. Steel seat ring integrally welded with the body.
