Milwaukee Valve

Milwaukee Valve BB2-102 2 in Bronze Butterfly Disc Valve FNPT

SKU CH-RX59-DG51B

A 2-inch bronze butterfly disc valve with a 316 stainless steel disc, FKM liner and lever handle rated for 175 psi and 30 to 275 °F

  • TypeOther
  • Rated for 175 psi water pressure for reliable shut-off
  • Operates from 30 to 275 °F for hot and cold lines
  • 316 stainless steel disc resists corrosion in aggressive water
  • FKM liner provides chemical compatibility and tight sealing
  • Lever handle gives quick quarter-turn operation for easy control

Application Suitability

The 2-inch bronze butterfly disc valve is designed for plumbing and hydronic systems that require a reliable shut-off or throttling point. It serves installers and maintenance crews working on water lines where the pressure does not exceed 175 psi and the fluid temperature stays between 30 and 275 degrees Fahrenheit. The FNPT threaded ends allow direct connection to standard iron pipe threads without additional adapters.

User Fit

This valve suits projects that need a bronze body with an FKM liner and a 316 stainless steel disc for chemical compatibility. It is not intended for gas service beyond the listed AGA approval or for systems that operate above the stated pressure and temperature limits. Buyers who need a different pipe size, a wafer or lug body style, or an actuated option should look at other models.

Deciding Specification

The pipe size of 2 in combined with the 175 psi maximum water pressure rating determines whether this valve matches the design conditions of the circuit. Confirm the system pressure and temperature fall inside the 30 to 275 degrees Fahrenheit range before specifying the part.

Questions about this item

Will the FKM liner or 316 stainless disc need replacement after years of hot water service?

The FKM liner and 316 stainless steel disc resist corrosion across the 30 to 275 °F range, so replacement is unlikely under normal conditions.

Does the 175 psi pressure rating become the limiting factor before the 275 °F temperature limit?

Yes, the 175 psi maximum water pressure is the first constraint under sustained high-pressure flow.

Does the bronze body or lever handle get hot enough to require insulation during all-day operation at 275 °F?

The bronze body will reach fluid temperature, so external insulation is recommended for personnel protection at the upper end of the 30 to 275 °F range.
