Six-Inch Wafer Butterfly Valve

The Milwaukee Valve MW222B is a six-inch wafer-style butterfly valve built for water control in commercial and industrial piping systems. It uses a cast-iron body with a Buna-N liner and a ductile-iron disc to handle flow regulation duties. The lever handle provides manual on-off and throttling operation.

Check Pressure Temperature And Flange Pattern

Verify that your system pressure does not exceed 200 psi and that the operating temperature stays between 10 and 180 degrees F. Confirm the mating flanges match the 9-1/2 inch bolt circle with two 3/4-10 lug holes. Ensure the pipe size is exactly six inches for proper wafer alignment.

Fits Between Flanges For Inline Shutoff

The wafer body slips between two companion flanges and is secured by the existing bolting hardware, so no separate valve flanges are required. The cast-iron construction handles water service within the rated pressure and temperature range. The lever handle frees up actuation space compared to gear-operated units.

Questions about this item

Does the MW222B butterfly valve include mounting hardware or must bolts and gaskets be purchased separately?

The valve body, ductile iron disc, Buna-N liner and lever handle are supplied; mounting bolts and flange gaskets are not included and must be sourced separately.

When should I choose the 200 psi wafer version instead of a lugged or higher-pressure model?

Select this wafer-style valve for 6-inch pipelines operating up to 200 psi water pressure between 10 and 180 °F where a compact, between-flanges fit is required.

What does the 200 psi rating mean once the valve is installed in a 6-inch line?

It indicates the maximum non-shock cold-water pressure the cast-iron body and Buna-N liner can withstand continuously at temperatures up to 180 °F.
