About Backflow-Prevention Valves

Threaded Check Valves
Male Inlet × Male Outlet
These valves open to allow flow in one direction and close when flow stops or reverses.
316 stainless steel valves have the best corrosion resistance.
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.
For technical drawings and 3-D models, click on a part number.
