Valve sizing and pressure fit
This Milwaukee Valve MW222B is a wafer-style butterfly valve built for 2 inch piping systems. It suits installers who need a compact shut-off device rated for 200 psi water service between 10 and 180 degrees Fahrenheit.
Flange pattern and liner check
Verify that the mating flanges provide a 4 3/4 inch bolt circle with two 5/8-11 lug holes. Confirm the Buna liner is compatible with the fluid being handled and that the nickel-plated ductile iron disc meets the application's corrosion requirements.
Wafer installation and lever operation
The wafer body slides between companion flanges and requires no separate flange set, freeing space in tight manifolds. The lever handle provides manual quarter-turn control without an actuator, and the design follows MSS-SP25, MSS-SP67 and API-609 standards for interchangeable fit.

Questions about this item
Does the MW222B come with bolts or gaskets for the 4 3/4 in bolt circle?
The valve body includes the 5/8-11 lug pattern for the two bolt holes; mounting bolts and flange gaskets are sold separately.
When should I pick the Buna liner over another material?
Buna handles water from 10 to 180 Degrees F at 200 psi, making it the standard choice for general HVAC and irrigation service.
What does the 200 psi rating mean once the valve is installed?
It is the maximum non-shock cold-water pressure the cast-iron body and nickel-plated ductile-iron disc can hold at the rated temperature range.
