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.
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.
