Flange Insert valves are the ultimate check valves in flanged systems. They provide the simplest most economical way to install check valves 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 flanged joint. See additional installation guidelines or consult the factory for more information.
Flange Insert valves are designed to fit between two mating ANSI flanges. The “Spring Housing” designated by the “A” dimension is designed to be inserted into the upstream pipe, thereby centering it in the pipe. Therefore, there must be clearance between the spring housing and the pipe or flange. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe or Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe or Class 600 flanges.
Flange Insert valves can be used as check valves, low pressure relief valves, and vacuum breakers by simply using different spring settings.
