1-1/2" Bronze Y Check Valve

The Milwaukee Valve 1509Y is a sweat-by-sweat bronze swing check valve built for 1-1/2 inch copper piping in hydronic or potable-water systems. It installs horizontally or vertically and provides automatic flow control without external power.

76 gpm capacity with .5 psi cracking pressure

The Y-pattern body delivers a rated flow of 76 gpm while opening at only .5 psi differential, giving strong headroom for typical residential and light-commercial circulation loops. The 300 psi water-pressure rating at 150 °F and 150 psi steam rating define the upper limits before the bronze seat and seal risk accelerated wear.

Bronze body rated to 425 °F and -20 °F

The all-bronze construction withstands continuous temperatures up to 425 °F and down to -20 °F without soft-seal degradation. The metal-to-metal seat operates silently under normal flow velocities and adds no measurable power draw to the system.

Questions about this item

Will the 1-1/2" sweat connections on this bronze Y check valve mate with my existing copper piping?

Yes, the valve uses sweat x sweat connections sized for 1-1/2" copper tube so it solders directly to matching pipe without adapters.

How can I verify the 1509Y is sealing properly after I solder it in line?

Pressurise the system up to 300 psi at 150 °F and confirm no leakage past the bronze seat; the swing disc should open at .5 psi cracking pressure and close silently when flow stops.

Does the 1509Y come with solder, flux or pipe hangers, or must I buy them separately?

The box contains only the bronze Y-pattern check valve body with integrated bronze seat and disc; solder, flux, hangers and any required pipe are purchased separately.
