Milwaukee Valve BA-475BMS brass ball valve

This two-way manual ball valve uses a brass body with a chrome-plated brass ball for controlling water or combustible gases. The straight inline design features 1/4 inch FNPT connections and a full-port opening for unrestricted flow. A locking handle prevents accidental operation during service.

Full-port design and locking handle

The full-port ball matches the pipe inner diameter to minimise pressure drop across the valve. A locking handle secures the valve in the open or closed position, reducing the risk of unintended actuation in vibration-prone installations. The two-piece body construction allows straightforward inline maintenance.

600 psi pressure rating

Rated for 600 psi water, oil and gas service and 150 psi saturated steam, this valve suits high-pressure plumbing and industrial lines. Vacuum service is rated to 29.92 in Hg for evacuation tasks. Buyers needing a lower pressure rating or a non-locking handle should select a different model.

Questions about this item

Will the chrome-plated brass ball or PTFE seats need periodic replacement in a water system?

The chrome-plated brass ball and PTFE seats are designed for the valve's service life; no scheduled replacement interval applies for normal water or gas service.

What pressure limit is reached first when the valve runs continuously at its 600 psi rating?

The 600 psi maximum operating pressure is the primary limit; the 150 psi steam rating and 29.92 in Hg vacuum rating apply only under those specific conditions.

Does the brass body or handle become hot to the touch during all-day operation with 150 psi steam?

At the 150 psi steam rating the brass body will reach steam temperature; the locking handle is metal and will also become hot, so insulation or protective gloves are recommended.
