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.

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.
