Single Disc Wafer Check Valve Short Pattern PTFE Seat Tight Shut
Off Hastelloy Alloy 20 Monel
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.

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
Self centering in pipeline due to controlled outside diameter,
enables easy installation.
