For more durability than plastic, these valves have a metal body. They meet NSF/ANSI 61 for drinking water service. All open to allow flow in one direction and close when flow stops or reverses.
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.
