Single Disc Swing Check Valve

Our check valve models IVC and IVCT are single plate swing check valve, short pattern conforming to API 6D and ANSI B16.10 face to face dimensions. The valve has a simple but robust construction with total reliability. The low inertia disc design enables the valve to open or close at a very low differential pressure making it ideal for pump discharge duties etc. The short face to face dimensions and low weight can reduce the number of pipe supports. Either slip on or weld neck flanges are suitable for the range, the IVC model being supplied with internal gaskets. Gaskets are recommended for the IVCT model.

Conformity to codes and standards:

Complies with the requirements of European Pressure Equipment Directive PED 97 / 23 / EC
Complies with the requirements of ATEX 94/9/EC

Design & face to face dimensions	API 6D / ANSI B16.10
Valve testing	API 598

Features

Very low face to face dimensions hence space required for mounting is less than 10% of 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.
