Milwaukee Valve CW223E 4 In Butterfly Valve Wafer Cast Iron
Wafer-style butterfly valve with cast iron body rated for 200 psi water pressure and -30 to 250 °F temperature range
- Wafer-style cast iron body fits between flanges without extra gaskets
- EPDM liner handles -30 °F to 250 °F water service
- Aluminum-bronze disc resists corrosion in 200 psi systems
- Lever handle provides direct manual control with two-bolt mounting
- Meets ABS standard for 4-inch pipe installations
Valve Purpose and Fit
This Milwaukee Valve CW223E is a 4-inch wafer-style butterfly valve built for water control in commercial and industrial piping. The cast iron body and EPDM liner suit potable water and general HVAC duty where a compact between-flanges fit is required.
Sustained Pressure and Temperature Behaviour
The valve is rated for a maximum water pressure of 200 psi across a temperature range of -30 to 250 degrees F. The aluminum bronze disc resists corrosion during continuous exposure, while the lever handle provides manual throttling without actuator hysteresis.
Installation Checks Before Ordering
Verify that the mating flanges match the 7 1/2 inch bolt circle with two 5/8-11 lug holes. Confirm the pipe schedule allows the wafer body to seat fully and that the media is compatible with EPDM at your operating temperature. Ensure adequate lever clearance for quarter-turn operation.

Questions about this item
How much heat does the cast iron body and EPDM liner handle during continuous hot water service?
The valve is rated for a temperature range of -30 to 250 degrees F, so the cast iron body and EPDM liner are designed to handle sustained hot water up to that limit.
What flange specification must my existing piping match for the 7 1/2 inch bolt circle and 5/8-11 lugs?
The wafer body has two bolt holes on a 7 1/2 inch bolt circle with 5/8-11 lug threads, so your flanges must align with that pattern and thread size.
Will the aluminum bronze disc resist corrosion if I keep my older iron pipe sections downstream?
The disc is made from aluminum bronze alloy, which provides corrosion resistance compatible with typical iron piping systems in water service.
