The IVSCV range of check valves offers optimum solution for back flow prevention in liquid and gas lines. Our special design feature provides a rugged construction, reliable operation and long service life. The valve finds applications in various segments of the process industries covering chemical, petrochemicals, pharma, steel, alumina,   power plants and common utilities.

The design offers a low pressure drop operation, which makes the valve more energy efficient. Pressure sealed bonnet design is incorporated for high pressure applications for reliable sealing. Valve can be provided with a external dashpot arrangement to provide non-slam operation, ideal to prevent water hammer.

Features :

• The product designs are in accordance to ASME B16.34 / BS 1868 / IBR with reliable sealing & sturdy construction to ensure excellent performance.
• Suitable for the horizontal & vertical pipe runs”NON-SLAM” arrangement i.e. Dash Pot arrangement can be provided on request.
• All trim material available as per API 600.
• Pressure sealed bonnet for ASME #900 and above to provide excellent sealing against increased line pressure.
• Full range of Body / Cover / Bonnet & Trim material available.
• Valves are available in flange end & butt weld end connections (other end connections can be provided on request).

Intervalve check valve models IVC and IVCT are primarily single plate swing check valve with a short pattern wafer body conforming to the API6D and ASME B16.10 face to face dimensions. The valve has a simple but reliable and robust construction. The low inertia disc design enables the valve to open or close with a very low differential pressure which make them ideal for services operating under low differential pressures.

The valve is ideal for pump discharge duties. The eccentric mounted hinge pin in combination with the disc seat guarantees a positive shut off of the returning media.

The short face to face dimensions and low weight allows a simple space saving installation between the mating companion flanges. The valves are suitable for mounting between weld neck or slip on type companion flanges of different standards. The need for flange gaskets during installation is totally eliminated in the case of IVC model due to the in-built face sealing ‘O’ rings provided on the sealing face. Gaskets are recommended while installing IVCT model valves.

Key Features:

• Very low face to face dimensions hence space required for mounting is less than 10% of that conventional valves.
• Very low weight-total weight is only approximately 1/6 the weight of a conventional check valve.
• Short wafer body enables mounting the valve with shorter length fasteners of lesser number compared to flanged swing check valve. Approximately 50% saving in cost of fasteners.
• Considerable secondary advantages resulting in substantial savings in handling, packing, transportation, installation and maintenance.
• Saving in terms of overall length required for piping.
• Tightening torque to be applied on the companion flange bolting is lower due to face sealing O-rings.
• Practically maintenance free due to fewer number of parts and simple construction.
• Self centering in pipeline due to controlled outside diameter, enables easy installation.

The IVDPCV is a spring loaded Dual Plate check valve uniquely designed for applications. The constructional feature makes the valve much smaller in size, lighter in weight & makes it much feasible in operation as compared to conventional swing check valve.

IVDPCV valve employs dual spring loaded plates / disc hinged on a central hinge pin. It operates on the differential pressure between fluid flow pressure & spring torsion pressure. As the flow pressure reduces, the plates tends to close with a cushion effect by spring torsion force thereby restricting the reversal of fluid flow.

Key Features:

• The product designs are in accordance to ASME B16.34 / API 594 with reliable sealing & sturdy construction to ensure excellent performance.
• The constructional feature reflects on the compactness of the valve by smaller volume, shorter length & even lighter weight.
• Suitable for the horizontal & vertical pipe runs.
• These valves can be provided with soft & metal seat.
• Various end connections such as wafer / wafer lugged / double flange.
• Long life & trouble free operation.
