Prevent vacuum loss with these airtight, leakproof valves. They 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.

To prevent flashback in flammable gas pipelines, an internal flame-arresting element absorbs the heat from a fire to extinguish the flame. These valves are commonly used in pilot lines connected to waste gas burners.
