Grey Stainless Steel IVDXR Butterfly Valve, For Industrial, Certification : ISI Certified

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.

Key Features:

• Perfectly machined stainless steel seat ring with specially designed sealing profile of the rubber ensures continued tight shut off sealing and makes it an ideal choice for the flow isolation and shut off duties.
• The double offset disc design ensures minimal seat wear and provides excellent throttling capabilities, which makes it an ideal choice for flow control duties.
• Adjustable mechanical stopper provided on valve body prevents over travel of disc and ensures precise closing.
• Actuator (operator) mounting flange standardized to ISO 5211 with provision of locational spigot, ensures direct mounting of actuators and gear boxes without any radical loading of shafts.
• Both Drive end and non drive end shafts are fully blowout proof and guided by self lubricated bush bearings.
• Axial thrust bearing provided on valves, ensures precise positioning of the disc and prevents unequal loading of the valve seat.
• Special shaft sealing arrangement ensure zero fugitive emission and enables field replacement of shaft sealing elements.
• The seat (sealing element) provided on the disc is fully field replaceable and ensures optimum seating / unseating torque.
• A choice of seat materials makes the valve suitable for gas or liquid services with a host of applications.
