1/2" Y Swing Check Valve

The Milwaukee Valve 507 is a 1/2 inch Y-pattern swing check valve designed for plumbing and hydronic systems that require automatic backflow prevention. Its bronze body and bronze seat handle water, oil, or gas in residential and light-commercial piping.

600 psi water and 300 psi steam ratings

The valve operates up to 600 psi water pressure at 150 degrees F and 300 psi saturated steam, with a temperature range from -20 degrees F to 550 degrees F. Flow capacity reaches 10 gpm, and the cracking pressure sits between .750 and 1.000 psi.

FNPT ends and mounting orientation

Verify that your piping uses 1/2 inch female NPT threads to match the FNPT x FNPT connections. The 2.625 inch overall length must fit the available space, and the line must be installed horizontally or vertically as specified for proper swing operation.

Questions about this item

Which size and pressure rating should I select for a 1/2" line handling up to 600 psi water pressure?

The 507 model in 1/2" size with FNPT x FNPT connections is rated for 600 psi water pressure at 150°F and 300 psi steam, matching those service conditions.

How does the 10 gpm flow rating translate when the valve is installed in a typical plumbing run?

The Y swing design allows 10 gpm flow with a low cracking pressure of .750 to 1.000 psi, so the valve opens quickly and adds minimal restriction in the line.

What does the FNPT x FNPT connection mean for installation and what pressure does it cap at?

FNPT x FNPT indicates female National Pipe Taper threads on both ends for direct threading onto male pipe ends, and the bronze body seals up to 600 psi water pressure at 150°F.
