1-1/4 Inch (in) Nominal Pipe Nominal Pipe Size and 0.500 Pound Per Square Inch (psi) Standard Cracking Pressure WV Style Wafer Insert Check Valve

The Wafer Insert (WV) valve is designed to fit between two mating ANSI flanges. Two gaskets are required, instead of the one normally used in a flanged joint. The “drop in” valve body fits inside the bolt circle for quick installation and removal in rigid piping applications where the use of the F1, F6, or FP is not practical. Many valves in this series can meet API 594 and/or B16.34 requirements. Consult the factory for more information.

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