INSERTA® ICFT Check Valves, Flange Type, provide an effective way to install a Check Valve or Fixed Orifice Flow Control Valve in a piping system that uses SAE 4-Bolt flange ports. These flange bodies include the INSERTA® ICT Thread-In Type Check Valves, with the option to include an INSERTA® IGT Guided Disc, Thread-In Type Check Valve on select sizes. The free flow direction is always from the surface with the seal to the surface without the seal. The nominal size INSERTA® ICT Thread-In Type or INSERTA® IGT Guided Disc, Thread-In Type Check Valve, matches the nominal flange size to meet most flow requirements for the given flange size. The ICFT Check Valves, Flange Type, 6132 and 6232 are also available with -24 size Check Valves for those applications that do not require the flow capacity of the -32 size.
A split flange connection should not be mounted directly to Face 1 of the valve. An optional IPS port spacer may be used between Face 1 of the valve and a split flange connection. The IPS port spacer is not required to mount a solid flange connection on Face 1 of the valve.
For those applications where one requires the free flow from the plain surface to the surface with the seal, the INSERTA® ICF/ IGS Check Valve Body or INSERTA® ICFS Check Valve Body with Support Member, Flange type, should be used with the INSERTA® ICS/ IGS Check Valve, Slip-In Type. The INSERTA® ICS/ IGS Check Valve, Slip-In Type, can be inserted from either end to permit free flow through the body in either direction. The ICF bodies use a larger nominal size INSERTA® ICS Check Valve, and is the check valve of choice in higher flow applications.
The INSERTA® IGT Guided Disc Thread-In Type Check Valve may be considered for in demanding applications that may subject the valve to considerable turbulence or higher cycling.
INSERTA® ICFT Check Valves, Flange Type, are all steel construction.
