2-inch Bronze Swing Check Valve

The Milwaukee Valve 510T is a 2-inch bronze swing check valve designed for plumbing and hydronic systems. It prevents backflow in horizontal or vertical pipe runs using an inline swing mechanism. The valve handles water, steam and compatible fluids in residential, commercial or light-industrial installations. Builders and maintenance engineers select it for reliable one-way flow control.

FNPT threaded ends with PTFE seal

Both ends use female NPT threads for direct connection to standard 2-inch pipe without extra fittings. The bronze body and bronze seat resist corrosion while the PTFE seat seal provides tight shut-off across the temperature range. The valve mounts in horizontal or vertical orientation, giving installers flexibility in tight mechanical rooms or exposed piping. Cracking pressure sits between .750 and 1.000 psi for prompt opening.

131 gpm flow capacity at 300 psi

The valve passes 131 gallons per minute at a maximum water pressure of 300 psi at 150 degrees Fahrenheit. Steam service is rated to 150 psi WSP and the assembly withstands temperatures from -20 to 406 degrees Fahrenheit. Specifiers confirm these limits against system design before ordering.
