6 in Wafer Butterfly Valve

The Milwaukee Valve MW222V is a 6 inch wafer style butterfly valve built for commercial and industrial piping systems. Its cast iron body and ductile iron disc handle water service up to 200 psi. The FKM liner provides chemical resistance across a temperature range of -20 to 300 degrees F. This valve suits installers who need a compact shut off device for flanged connections.

Thermals noise and power draw

As a manual valve the MW222V has no electrical consumption and produces no operational noise. The lever handle requires human force to operate so torque depends on line pressure and liner friction at the moment of actuation. Temperature extremes within the rated range do not create thermal expansion issues beyond normal piping design allowances. There are no moving electrical parts to generate heat.

Fit in a build

The wafer body fits between two flanges using two bolt holes on a 9 1/2 inch bolt circle with 3/4-10 lug diameter. No separate flange set is included so the installer must supply matching flanges gaskets and bolts. The compact wafer profile saves axial space compared to lugged or flanged valve bodies. This valve is not for systems requiring dead end service or downstream flange removal without line shutdown.

Questions about this item

How do I install the wafer-style butterfly valve with the 9 1/2 in bolt circle and two bolt holes?

Align the valve between flanges matching the 9 1/2 in bolt circle, insert two 3/4-10 bolts through the lugs, and tighten evenly in a cross pattern to avoid pinching the FKM liner.

What maintenance will the FKM liner and ductile iron disc need over time?

Inspect the FKM liner periodically for chemical attack or compression set, and check the ductile iron disc for corrosion; replace the liner if swelling or cracking appears.

At what pressure or temperature limit will the valve show stress first during sustained use?

The 200 psi water-pressure rating is the primary limit; sustained operation near 300 °F accelerates FKM aging, so pressure excursions above 200 psi will appear first.
