  • Lever handle provides direct manual control
  • Four-bolt pattern on 5 1/2 in circle simplifies installation

Product identity and intended use

The Milwaukee Valve ML232B is a lug-style butterfly valve designed for water distribution systems. It fits a 2 1/2 inch pipe and uses a lever handle for manual operation. The ductile iron body and disc provide mechanical strength in commercial and industrial piping.

Thermals noise and power draw

The valve operates passively with no electrical consumption or generated noise. Fluid temperature is rated from 10 to 180 degrees Fahrenheit. Maximum working pressure is 200 psi within that temperature range.

Decisive specification

The Buna-N liner determines chemical compatibility and temperature limits for the application. Verify that the media and operating conditions fall within the liner rating before installation. California Proposition 65 warnings apply to this product.

Questions about this item

How do I bolt the 2 1/2 in lug valve to a flange with a 5 1/2 in bolt circle, and what torque mistake do installers make?

Align the four 5/8-11 lug holes with the mating flange, insert studs through both flanges, and tighten in a star pattern to the flange specification; the common error is uneven torque that warps the ductile-iron body and leaks at the Buna-N liner.

Which component will need replacement first in water service between 10 and 180 Degrees F?

The Buna-N liner degrades before the ductile-iron disc or body, especially near the 180 Degrees F limit, so plan to replace the liner when sealing performance drops.

At what pressure does the 200 psi rating become the limiting factor during sustained operation?

Continuous service at or above 200 psi exceeds the valve’s maximum water pressure rating and will cause liner extrusion or body fatigue before temperature or cycle limits are reached.
