Industrial Gate Valve for Fluid Control

The Milwaukee Valve 2885-M is a 4-inch gate valve designed for regulating gas, oil and water in commercial and industrial piping systems. Its cast-iron body and bronze trim handle operating pressures up to 200 psi and steam pressures up to 125 psi. The outside screw and yoke stem with a wheel handle provides visible position indication for operators.

Replacing Lower-Class Flanged Valves

This Class 125 flanged valve upgrades installations that previously used lower-pressure gate valves or globe valves requiring frequent packing maintenance. The jump is worth it when the system demands a high flow coefficient of 945 Cv with minimal pressure drop across the fully open wedge. The bolted bonnet allows in-line servicing without removing the valve from the pipeline.

Integration into Flanged Piping Networks

The valve fits between standard Class 125 flanges and requires compatible gaskets and bolt sets for a leak-free seal. Brass stem material resists corrosion from condensate while the solid cast-iron wedge withstands debris in the media. The rising stem design frees up the need for external position sensors because gate travel is mechanically visible at the handwheel.

Questions about this item

What flange class and bolt pattern does the 4 in valve require for mounting?

The valve uses an ANSI Class 125 flange pattern; match the companion flange drilling and use a full-face gasket rated for 200 psi water or 125 psi steam service.

How do I install the bolted-bonnet OS&Y valve without damaging the bronze seats?

Clean flange faces, align the bolt holes, insert all bolts finger-tight, then torque in a star sequence to the flange standard; do not use the handwheel to force alignment.

Which internal parts will need replacement after extended service?

The bronze seat rings and bronze seal surfaces are the primary wear items; the solid cast-iron wedge and brass stem typically remain serviceable longer.
