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.

A real workhorse from the IV stables, IVGK model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with centric disc construction and is available in wafer type body pattern. 

The body liner which also functions as the soft seat, comes in either a replaceable version or an integrally molded (bonded) version and offers 100 % bi-directional sealing against vacuum to rated pressure of PN10 or PN16.

IVGE model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with a centric, rubber encapsulated disc construction  and is available in wafer lugged body pattern.

The body liner which also functions as the soft seat, comes integrally moulded (bonded) version and offers 100% bi-directional sealing against rated pressures of PN 10. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

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 camming 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 rangeability. 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 Edn. V by Bureau Veritas and TUV.

The IVR model Butterfly dampers, offered by Intervalve are essentially seatless Butterfly valves intended for low pressure gas lines and air lines. The lightweight construction with the narrow wafer body enables easy fitment of these valves in ducts, manifolds and exhaust lines without additional support or strengthening of pipe lines.
IVR valves are primarily intended for low-pressure large volume gas / air flow control applications. The absence of seat substantially reduces the valve operating torque requirements and makes the valve very effective for flow control / regulation duties. IVR is an ideal choice for furnace air flow and combustion control applications.
Even though the body is designed for a maximum pressure of 2.5 bar the maximum shut off pressure is limited to 0.5 bar only. The disc flap is held in position by a stub shaft with an axial locking arrangement provided on the top shaft. The top shaft sealing is through stuffing box type gland sealing arrangement, which is field adjustable.

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.

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.
