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-EN (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 Stainless Steel seat ring integrally welded with the body.

The most sought after design by desalination plants and utility installations, IVDF represents the state of the art rubber lined Flanged double valve, meeting all the user industry requirements.
The double flanged body pattern ensures precise installation in pipeline, and can be used as an end to the line valve if required. The unique feature of this valve, is its adaptability for lined pipes, due to negligible disc protrusion beyond the body laying length. The universal square top shaft on valves upto DN200, enables easy change over from hand lever operation to actuated operation when required.
