3-Inch Cast Iron Gate Valve
The Milwaukee Valve 2882-M is a 3-inch gate valve constructed from cast iron with ANSI Class 125 flanged connections. It is designed for controlling the flow of gas, oil, and water in industrial piping systems. The bolted bonnet and non-rising stem provide reliable operation where space above the valve is limited. This new component suits maintenance crews and plant engineers specifying shut-off hardware.
Pressure Ratings and Flow Capacity
The valve handles a maximum operating pressure of 200 psi for water, oil, and gas service, while steam service is rated at 125 psi. A coefficient of volume of 510 indicates high flow capacity with minimal restriction when the solid cast iron wedge is fully open. Bronze seat and seal materials support durability across the stated media. The ratings define the safe operating envelope for this specific model.
Replaces Worn Bronze-Seated Valves
This unit serves as a direct replacement for existing 3-inch Class 125 flanged gate valves that have worn seats or damaged wedges. The upgrade is worth it when the current valve leaks at the seat or the stem packing fails under system pressure. Brass stem construction resists corrosion better than plain steel alternatives in similar service. Buyers needing a rising-stem design or higher pressure classes must select a different model.

Questions about this item
Will the 200 psi rating and cast-iron body with Class 125 flange match my existing 3-inch steel piping without extra adapters?
The valve has a 200 psi operating pressure and 125 psi steam rating with ANSI Class 125 flanges, so it bolts directly to matching 3-inch Class 125 flanged pipework.
How can I confirm the non-rising stem and brass stem are operating correctly after installation?
Turn the handwheel and watch the gate move through the open-close cycle; the stem should not rise, and smooth rotation with no binding indicates proper function.
Does the box include the bronze seat and seal rings, or must I order them separately?
The valve ships complete with the bronze seat and seal rings already installed in the cast-iron body.
