Bronze Inline Check Valve

The Milwaukee Valve UP1509 is a 3/4 inch sweat low-lead bronze spring check valve designed for residential and commercial plumbing systems. It installs inline on copper tubing using sweat connections and allows flow in a single direction.

Spring cracking pressure range

The valve opens between 0.750 and 1.000 psi cracking pressure and must be mounted horizontally to operate correctly. It handles water pressure up to 300 psi at 150 degrees F and temperatures from -20 to 200 degrees F.

18 gpm flow capacity

This inline swing check valve delivers a maximum flow of 18 gpm through its bronze body and bronze seat. It is not rated for steam service, so installers needing steam-rated components must select a different valve.

Questions about this item

Should I choose a different size or pressure rating for my 3/4-inch copper line?

This valve is built for 3/4-inch sweat connections and handles up to 300 psi at 150 degrees F, so match those specs to your system requirements.

What does the 18 gpm flow rating mean when the valve is installed in my plumbing?

It indicates the valve can pass up to 18 gallons per minute through the 3/4-inch bronze body under normal operating conditions.

How does the sweat connection affect installation and pressure limits?

Sweat ends require soldering to copper pipe; the joint then supports the valve's 300 psi rating at 150 degrees F.
