The ultimate in high performance Butterfly valves, IV’s IVEX – series incorporates the ‘state of the art’ valve technology to out perform the competition. The double offset disc design nearly eliminates the seating wear due to the cam action of the disc during closing. The mechanical stopper provided on the valve body ensures precise valve closing every time to ensure specified seat tightness. The disc has a spherical profile and comes out of contact with seat in the initial opening itself.

The valve is available with 3 distinctly different seat design versions, viz. Soft seated, Fire safe and Metal to Metal seated with wafer or wafer lugged body option.

The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher range ability. This feature of IVEX series makes them ideal for the flow control / modulating duties. An adjustable gland box type shaft sealing arrangement permits on line adjustment of the packing to ensure zero leakage.

The fire safe version, IVEX – F model has been fire tested and certified as per the requirements API 607 standard by Lloyd’s Register of Shipping & API 607 Edition. V by Bureau Veritas and TUV.

Key Features:

• Double offset disc design with a spherical profile seat eliminates seat wear and ensures perfect sealing every time.
• Availability of wafer lugged body with through drilled or threaded holes.
• Available in 3 distinctly different seat version viz. PTFE seat, Fire Safe seat and Metal to Metal seated.
• Self- lubricated drive end and non-drive end bearings for IVEX–T and IVEX-F models and galling free metal bearing for IVEX-M versions.
• Stuffing box type gland sealing to enable field adjustment of shaft sealing.
• Gland packing standardised on graphoil rings (non-asbestos) to offer widest operating temperature range coupled with excellent media resistance.
• Metal seat standardised on Inconel 625 material to offer maximum temperature resistance and minimum seat deformation.
• Option of seat material for soft seated version in virgin PTFE or filled PTFE.
• Seat removal without disconnecting of shaft and disc.
• Split ring type thrust pad provided for the drive end shaft prevents axial movement of the disc as well as ensures the required ‘anti-static’ feature for the valve.
• IVEX-F model fire tested in presence of third party agencies as per latest version of API 607 standard.
• Special material of construction available optionally for specific services.

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.

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.

Key Features:

• Fully rubber lined body, with lining extending upto the flange contact face to make gasket free sealing.
• Ideal valve for installation with lined pipes, since the disc chord interference with pipe ID is negligible.
• Controlled compression of the gasket face offers optimum sealing and prevents gasket face crushing.
• Unique triple sealing system, for shaft sealing to ensure zero secondary leakage.
• Self lubricated PTFE lined bearings, for both drive end and non-drive end shafts, ensures minimum bearing friction.
• Bi-directional tight shut off sealing from vacuum to rated pressure.
• Excellent adaptability for actuated operation through standardized ISO top flange.
• Universal top square shaft enabling direct actuator fitment, after removal of Hand lever, for sizes upto DN200.
• Choice of seat and disc materials to suit media and operating conditions.
• Enables installation close to other pipe fittings, without disc interference.
• Preferred design for desalination plants, municipal water supply and Effluent plants.
• Adjustable bottom thrust pad / bearing for DN250 and higher to take care of axial thrust loading.
• DN600/DN650 size provided with “O Ring holder” type drive end shaft sealing arrangement for extra reliability.

Intervalve’s GKL series valves are designed to meet the demanding requirements of the general utility valve market with the HVAC segment in particular. IVGKL is a truly fit & forget valve, which requires minimal maintenance. The body liner which also functions as the soft seat, comes in an integrally molded (bonded) version and offers 100% bi-directional sealing. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

Key Features:

• Integrally molded seat liner on the body, which ensures excellent dimensional stability & guaranteed seat tightness.
• Seat liner extending on to the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
• Unique triple sealing system for shaft sealing ensures zero leakage of the media past the shaft seals.
• Narrow land disc ensures perfect sealing with least operating torque requirements.
• A fully universal body design ensures fitment of the valve between companion flanges of all popular standards (viz: ANSI, BS, DIN, JIS, IS etc. ).
• A ten position notch disc and handlever ensures locking of the valve in 8 intermediate position in addition to closed and open position. Handlever lockable through pad lock for tamper proof positioning.
• Body castings made of superior FG 260 grade cast iron to ensure additional strength.
• Valve disc made of ductile cast iron instead of cast iron to withstand against possible water hammer or pressure surges.
• A truly line size body bore to ensure maximum flow capacity with the lowest pressure drop.
• Shafts made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
• Both top and bottom shaft swiveling are guided by self – lubricated PTFE bearings.
