3-Inch Bronze Gate Valve for Fluid Control

The Milwaukee Valve 105 is a Class 125 bronze gate valve designed for controlling gas, oil, and water flow in piping systems. It features a 3-inch nominal size with female NPT connections for direct threaded installation. The non-rising stem and solid wedge design provide reliable shut-off performance in industrial and commercial applications.

Suited for Bronze-Compatible Systems.

This valve suits installers needing a bronze-bodied gate valve rated for 200 psi operating pressure and 125 psi steam service. The screw-in bonnet and wheel handle allow straightforward manual operation and maintenance. Buyers requiring flanged connections, rising-stem visibility, or pressure ratings above Class 125 should look at alternative valve designs.

Threads into NPT Piping, Frees Up Flange Hardware

The female NPT ends thread directly into matching pipe without flanges, gaskets, or bolt kits, simplifying assembly in tight spaces. Bronze construction throughout the body, bonnet, stem, wedge, seat, and seals ensures material compatibility across the assembly. The 536 Cv rating indicates high flow capacity when the solid wedge is fully open.

Questions about this item

What piping must I already have to install this 3-inch FNPT gate valve?

You need a 3-inch male NPT thread on the pipe or fitting so the valve's female NPT connection can screw on directly.

Will this Class 125 bronze valve handle the same 200 psi water pressure as my older steel gate valve?

Yes, the valve is rated for 200 psi maximum operating pressure and 125 psi steam, matching typical Class 125 service limits.

How can I confirm the non-rising stem is sealing properly after I thread it in?

Turn the wheel handle until it stops; the solid bronze wedge should seat fully and stop flow with a Cv of 536 when open.
