2-inch bronze swing check valve
The Milwaukee Valve 508 is a 2-inch bronze Y-pattern swing check valve designed for horizontal piping systems. It uses FNPT threaded connections on both ends and a chrome-cobalt seal to prevent back-flow in water and steam lines. The bronze body and seat resist corrosion in commercial and industrial plumbing installations.
131 gpm flow with 0.5–0.75 psi cracking pressure
The valve passes up to 131 gallons per minute while opening at a low cracking pressure between 0.500 and 0.750 psi. It handles water pressure up to 400 psi at 150 degrees Fahrenheit and steam pressure up to 200 psi. Operating limits extend from minus 20 degrees to 550 degrees Fahrenheit.
Horizontal mount with 5.875-inch face-to-face length
Installation requires a horizontal run with 5.875 inches of straight pipe clearance for the valve body. The FNPT threads connect directly to standard 2-inch pipe without flanges or special tools. The Y-pattern body reduces turbulence and provides a compact footprint in crowded mechanical rooms.

Questions about this item
Will the 2-inch FNPT threads on this 508 valve match the 2-inch schedule-40 pipe I already have in place?
Yes, the valve uses FNPT x FNPT connections sized for 2-inch pipe, so standard 2-inch NPT male threads will engage directly.
How can I confirm the Y-swing mechanism is opening at the correct cracking pressure once installed?
Apply upstream pressure between .500 and .750 psi; the disc should begin to lift within that range, indicating proper operation.
Does the bronze body and chrome-cobalt seal ship assembled, or do I need to supply any gaskets or thread sealant?
The valve arrives fully assembled with the bronze seat and chrome-cobalt seal installed; you only need pipe thread sealant for the FNPT connections.
