CHECK-ALL VALVE Style F1 316 Stainless Steel Flange Insert Valves CVF1HSSMT500SS

Check-All Valve Style F1 316 Stainless Steel Flange Insert Valve The Flange Insert (Styles 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? dimensions, 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. The Flange Insert valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
