Milwaukee Valve BB2-100 1/2 in Bronze Disc Valve

1/2 in Bronze Butterfly Disc Valve

The Milwaukee Valve BB2-100 is a 1/2 inch bronze butterfly disc valve designed for water control in residential or light commercial plumbing systems. It connects via FNPT threads and operates with a lever handle for manual flow regulation. The valve body uses bronze construction with a 304 stainless steel disc and an FKM liner for fluid compatibility. It carries AGA, cCSAus, cULus and UL listings for code compliance.

Pressure and Temperature Operating Limits

This valve handles a maximum water pressure of 175 psi and a temperature range from 30 to 275 degrees Fahrenheit. The FKM liner and 304 stainless steel disc maintain integrity within these boundaries. Operation outside the stated pressure or temperature range is not supported by the listed standards. The 1/2 inch pipe size defines the flow capacity of the connection.

Flow Control Suitability and Constraints

The valve comfortably handles on-off and throttling duties for standard hot and cold water lines within the rated pressure and temperature envelope. It runs out of headroom in high-pressure steam, cryogenic or aggressive chemical service where the FKM liner or bronze body would exceed their limits. Buyers needing larger diameter connections or higher pressure ratings must select a different model.
