F1/F6/FP Flange Insert Valve

Brand: Check-All Valve Manufacturing Company

The Flange Insert (F1, F6, FP) valves are the ultimate check valve in flanged systems.

They provide the simplest and most economical way to install check valves in a piping system. The valve body helps position itself while bolts are being installed and tightened. Two gaskets are required instead of the one normally used in a flanged joint. 

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 helping to center 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 with Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe with Class 150, 300 or 600 flanges. 

The Flange Insert valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
