4-inch cast-iron gate valve

This Milwaukee Valve 2882-M gate valve controls flow of gas, oil or water in industrial piping. Its cast-iron body and bronze seat suit general service lines up to 200 psi. The non-rising brass stem and bolted bonnet simplify maintenance in tight spaces. A hand wheel operates the solid cast-iron wedge.

Class 125 flange pressure limits

The ANSI Class 125 flange rating sets the practical ceiling at 200 psi for water, oil or gas and 125 psi for steam. Exceeding those pressures risks flange leakage or body damage. The bronze-on-bronze seal holds within the stated range but is not rated for higher classes. Install only where system pressure stays at or below the listed figures.

945 Cv flow coefficient

A coefficient of volume of 945 means the valve passes high volume with minimal pressure drop when fully open. Systems needing significantly lower or higher flow capacity should select a different Cv rating. This single figure determines whether the valve matches the pipeline’s hydraulic design.
