Check & Vent Valves | Boiler Supplies Check Valves by Check All Valves Check-All Style FIV - Flange Insert Valve
The Check-All Valve Flange Insert Valve is the ultimate check valve in flanged systems. Designed to be inserted between two mating ANSI flanges, it provides the simplest most economical way to install a check valve in a piping system. The valve body automatically positions the valve and holds it in place while bolts are being installed and tightened. All that is required is two gaskets in place of the one normally used in a flange joint.
Check-All Valves Flange Insert Valves are available in the following materials and sizes:
Flange Insert Valves are available in most metal alloys for use with ANSI class 150, 300 and 600 flanges. Brass valves are for use with the ANSI class 150 and 300 flanges.
Flange Insert Valves can be used as check valves, low pressure relief valves and vacuum breakers by simply using different spring settings.
Flange Insert Valves are available in Titanium, HASTELLOY Alloys, MONEL Alloys, Alloy 20 and many other alloys.
