Bronze Swing Check Valve

The Milwaukee Valve 1509 is a 2 inch bronze swing check valve designed for plumbing systems that require automatic backflow prevention. It suits installers working on residential or light commercial water and steam lines where a reliable, inline non-return device is specified.

Sweat Connection Inline Fit

The valve uses sweat by sweat connections for direct soldering into copper pipework, eliminating the need for threaded adapters or flanges. Its inline swing design keeps the flow path straight, reducing pressure drop and freeing space in tight pipe runs compared with bulkier check mechanisms.

Sustained Temperature and Pressure

Rated for continuous service up to 406 degrees Fahrenheit and 200 psi water pressure at 150 degrees Fahrenheit, the valve also handles 125 psi steam pressure. The bronze seat and seal maintain sealing integrity across thermal cycles, with a cracking pressure between .500 and .750 psi that stays consistent during prolonged operation.

Questions about this item

At what pressure does the 1509's bronze disc start to open?

The valve begins to open between .500 and .750 psi cracking pressure, so the disc lifts with very little flow resistance.

Will the bronze body and seat handle continuous 150 °F water at the rated 200 psi?

Yes, the bronze construction is rated for 200 psi at 150 °F and up to 406 °F maximum temperature, so all-day hot-water service is within limits.

Does the 2" sweat connection mean I need copper pipe and solder ready?

Correct — both ends are sweat fittings, so you will need 2" copper tube, flux and solder to make the joints.
