  • Operates from -20 to 550 Degrees F in horizontal or vertical mounting

1-1/2" FNPT Bronze Swing Y Check Valve

The Milwaukee Valve 507 is a 1-1/2 inch FNPT bronze swing Y check valve designed for plumbing systems that require automatic backflow prevention. It suits installers who need a reliable non-return valve for water or steam lines up to the rated pressures.

Sustained pressure and temperature performance

The valve handles a maximum water pressure of 600 psi at 150 degrees F and a maximum steam pressure of 300 psi WSP. Its operating temperature range spans from -20 degrees F to 550 degrees F, and the cracking pressure sits between .750 and 1.000 psi for consistent sealing under continuous service.

Installation orientation and sealing considerations

The Y-pattern body permits horizontal or vertical mounting, giving flexibility during pipe layout. The chrome-cobalt seal material and bronze seat require clean threads and proper pipe compound to avoid leaks; debris in the line can prevent the swing disc from seating fully.

Questions about this item

Does the 550 °F temperature rating of the bronze body mean the valve runs hot to the touch during continuous operation?

The 550 °F figure is the maximum fluid temperature the bronze body and chrome-cobalt seal can withstand, not the surface temperature; actual housing warmth depends on the fluid temperature and pipe insulation in your system.

What piping and orientation do I need to install this 1 1/2" FNPT Y-pattern swing check valve?

It requires 1 1/2" female NPT threads on both inlet and outlet and can be mounted horizontally or vertically with flow in the direction of the arrow on the body.

Will the 0.75–1.0 psi cracking pressure of this check valve work with the low-head gravity feed on my older tank system?

Yes, the 0.75 to 1.00 psi cracking pressure is low enough for gravity-fed lines; the bronze seat and 76 gpm flow capacity also match older piping without excessive restriction.
