Application & fit

The Milwaukee Valve BA-485BMS is a 1-1/4 inch sweat brass ball valve designed for inline installation in plumbing systems. It suits installers who need a two-way manual shut-off for water or combustible gases in residential or light commercial pipework.

Pressure & sealing

The valve body is a two-piece brass construction with a chrome-plated brass ball and full-port opening. It is rated for 600 psi maximum operating pressure and holds a vacuum service rating of 29.92 in Hg, with a non-locking handle for straightforward quarter-turn operation.

Connection method

This model uses a sweat (solder) connection, so it is not compatible with threaded, press-fit or push-fit piping systems. Buyers who need a different end connection or a locking handle should select an alternative valve.

Questions about this item

How do I sweat the 1-1/4" brass body without damaging the chrome-plated ball?

Clean the copper tube ends, apply flux, assemble the valve fully open, and heat the joint evenly so solder flows into the cup; keep the ball open during heating to prevent seat distortion.

What parts will need replacement after years of water service?

The PTFE seats and stem packing are the wear items; if leakage appears at the stem or across the closed ball, replace the seat and packing kit rather than the whole valve.

At what pressure does the 600 psi rating become the limiting factor during sustained use?

The 600 psi operating limit is the first ceiling; sustained pressure above that rating will exceed the valve's design margin before temperature or vacuum limits are reached.
