Milwaukee Valve 1510T 1/2 Swing Check Valve 2.5625 in

Check valve for 1/2 inch plumbing

The Milwaukee Valve 1510T is a bronze inline swing check valve sized for 1/2 inch sweat connections. It prevents reverse flow in hot- and cold-water lines with a cracking pressure between .750 and 1.000 psi. The PTFE seal operates from -20 to 406 degrees F and handles up to 300 psi water pressure at 150 degrees F. It mounts horizontally or vertically and delivers 10 gpm flow capacity.

Fits standard residential supply lines

This valve suits installers who need a compact bronze check valve for 1/2 inch copper tubing in horizontal or vertical runs. It is not for systems requiring larger pipe diameters, flanged or threaded connections, or higher steam pressures than 150 psi WSP. Builders needing a different cracking pressure range or a non-swing mechanism should look elsewhere.

Sweat ends simplify copper installs

The sweat-by-sweat ends join directly to 1/2 inch copper without extra fittings, saving space in tight wall cavities. Bronze body and PTFE seal resist corrosion across the full temperature span, freeing the installer from selecting separate high-temp gaskets. Horizontal or vertical mounting flexibility lets the valve adapt to existing pipe routing without rework.
