The Wafer Insert (WV) valve is designed to fit between two mating ANSI flanges. Two gaskets are required, instead of the one normally used. 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 are not practical. Many valves in this series meet API 594 and/or B16.34 requirements. Consult the factory for complete details.

WV valves can also be used as a low pressure relief valve or vacuum breaker by simply using the desired spring settings.
