    Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.
    Lockable lever handles can be fixed in place with a padlock (not included).
    Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

    Lug valves can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.
    Lockable lever handles can be fixed in place with a padlock (not included).

    Flanged Check Valves

    Bolt these valves to ANSI flanges. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.

    Flange-Mount Check Valves

    Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint. ANSI flanges are sold separately. All valves open to allow flow in one direction and close when flow stops or reverses.
