Milwaukee Valve ML222B Lug Butterfly Valve

This Milwaukee Valve ML222B is a lug-style butterfly valve built for water-service piping. Its cast-iron body and ductile-iron disc handle 200 psi at temperatures from 10 to 180 degrees F. A Buna-N liner and lever handle complete the assembly for on-off flow control.

Installers needing 2 1/2 in lug connections

The four-hole bolt pattern on a 5 1/2 in circle with 5/8-11 lug threads suits flanged piping that matches those dimensions. Systems requiring a different bolt count, circle diameter, thread size or a liner rated beyond 180 degrees F will need another valve.

200 psi pressure rating at 180 degrees F

This single figure confirms whether the valve meets the design pressure and temperature of the intended water circuit. If the system operates above 200 psi or exceeds 180 degrees F, the ML222B is not suitable.

Questions about this item

What pipe size and bolt-circle diameter must my existing flanges match for the ML222B to bolt up?

The valve fits 2 1/2 in pipe and a 5 1/2 in bolt-circle with four 5/8-11 lug holes.

Will the Buna-N liner and ductile-iron disc handle the same 10 to 180 °F water temperatures as my older cast-iron valves?

Yes, the Buna-N liner is rated for 10 to 180 °F, matching typical cast-iron valve service ranges.

How can I confirm the lever handle is sealing at the full 200 psi rating after installation?

Pressurise the line to 200 psi and verify no leakage past the disc while the lever is fully closed.
