3/4" Bronze Swing Check Valve

The Milwaukee Valve 1509 is a 3/4 inch bronze swing check valve with sweat connections for copper piping. It allows flow in one direction and closes automatically to prevent backflow in plumbing and hydronic systems. The valve operates horizontally and handles water up to 200 psi at 150 degrees Fahrenheit. It is built for new residential or light commercial installations.

Suitable uses and limits

This valve suits installers needing a bronze body with sweat ends for horizontal copper lines carrying water or low-pressure steam. It is not for vertical piping runs, high-pressure steam above 125 psi, or systems requiring a softer seat for tighter shut-off. Buyers needing flanged, threaded, or press connections should look at a different valve body style.

18 gpm flow capacity

The published flow rate is 18 gallons per minute through the 3/4 inch port. This single figure determines whether the valve can pass the required volume without excessive pressure drop in the circuit. Match this number to the system design flow before purchasing.

Questions about this item

What pipe size and connection type does the 1509 swing check valve require?

The valve fits 3/4 inch copper tubing and uses sweat x sweat connections on both ends.

How must the valve be oriented during installation, and what is the common mistake?

Install the valve horizontally with the hinge pin on top; installing it vertically or upside down will prevent the disc from sealing properly.

When should the bronze seat and disc be inspected or replaced?

Inspect the seat and disc if leakage occurs or after prolonged exposure to temperatures near 406 °F or pressures above 200 psi at 150 °F.
