  • Lug-style mounting fits 8-bolt patterns

  • EPDM liner handles -30 to 250 °F water
  • Ductile iron body rated for 200 psi pressure
  • Aluminum bronze disc resists corrosion in service

Valve type and pipe size

The Milwaukee Valve ML-233E is a 4-inch lug-style butterfly valve designed for water piping systems. It uses a ductile iron body with an EPDM liner and an aluminum bronze alloy disc to handle flow control in commercial and industrial installations. The lever handle provides direct manual operation for on-site adjustments.

Compatibility checks before ordering

Verify that the mating flanges match the 8-hole pattern on a 7 1/2-inch bolt circle with 5/8-11 lug threads. Confirm the system pressure does not exceed 200 psi and that the operating temperature stays within the -30 to 250 degrees F range. Ensure the pipe material and fluid type are compatible with ductile iron, EPDM and aluminum bronze components.

Behaviour under sustained load

The valve body and liner are rated for continuous service at the full 200 psi pressure limit across the stated temperature span. EPDM retains sealing properties during prolonged exposure to water within the temperature range, while the aluminum bronze disc resists erosion from steady flow. The ductile iron body maintains structural integrity under constant mechanical and thermal cycling.

Questions about this item

Does the ML-233E 4-inch butterfly valve ship with a gasket and bolts, or must they be purchased separately?

The valve body, EPDM liner, aluminum-bronze disc and lever handle are supplied; flange gaskets and eight 5/8-11 bolts are not included and must be sourced separately.

Should I choose this lug-style valve or a wafer version for a 4-inch ductile-iron line?

Choose this lug-style ML-233E when the piping system requires dead-end service or the ability to remove downstream pipe while the upstream side remains pressurised.

What does the 200 psi rating mean once the valve is installed in a hot-water loop?

The 200 psi rating applies across the full -30 °F to 250 °F temperature range, so the valve holds that pressure even at maximum hot-water temperature.
