Product identity

The Milwaukee Valve ML232B is a lug-style butterfly valve built for 3-inch piping systems. It uses a ductile-iron body and disc with a Buna-N liner and a lever handle for manual operation.

Suitable applications

This valve suits water-service installations that operate between 10 and 180 degrees Fahrenheit at pressures up to 200 psi. It is not intended for media outside that temperature range, for pressures above the rated limit, or for automated actuation without additional hardware.

Capacity and headroom

The four-bolt lug pattern on a 6-inch bolt circle with 5/8-11 threads provides secure mounting to compatible flanges. The 200 psi pressure rating and 180-degree temperature ceiling define the operational envelope; service beyond those limits requires a different valve specification.

Highlights

  • Buna-N liner seals effectively across 10 to 180 °F temperature range

Questions about this item

What pipe size must the existing line be for this 3 in lug-style valve to bolt up?

The valve is built for a 3 in pipe size with a 6 in bolt circle and four bolt holes, so the mating flange must match that pattern.

Will the Buna-N liner hold up if the system runs near 180 °F?

The liner is rated for a temperature range of 10 to 180 °F, so continuous operation at the upper limit is within specification.

How can I confirm the disc is sealing properly after installation?

Pressurize the line up to the 200 psi rating and verify no leakage past the ductile-iron disc while the lever handle is fully closed.
