Bronze Gate Valve 1/2 Inch

This Milwaukee Valve 105 is a 1/2 inch bronze gate valve rated Class 125 for general plumbing service. It handles water, oil and gas media with a non-rising stem and solid bronze wedge. The female NPT connection suits standard pipe threads in residential and light commercial systems.

Replaces Worn Bronze Gate Valves

Install this valve when an existing bronze gate valve leaks past the seat or the stem packing fails under pressure. The 200 psi cold working pressure and 125 psi steam rating match typical Class 125 specifications. The jump is worth it when the old body shows corrosion or the wheel handle no longer operates smoothly.

Sustained Pressure Service

Under continuous load the bronze body, stem, wedge and seat maintain sealing integrity up to the rated pressures. The 17.6 Cv coefficient indicates flow capacity through the fully open port. The screw-in bonnet and non-rising stem design suit installations where vertical space is limited and frequent cycling is not required.

Questions about this item

What thread size and type does the 1/2-inch Milwaukee Valve 105 use for piping connections?

It has a 1/2-inch female NPT thread on each end, so standard male NPT pipe nipples or fittings screw directly into the valve body.

How should the bronze screw-in bonnet be oriented and sealed during installation?

Install the valve with the wheel handle accessible, tighten the bonnet by hand then snug it with a wrench, and apply PTFE tape or pipe dope only to the external NPT pipe threads — never to the bonnet joint.

When should the solid bronze wedge or seat be inspected or replaced in water service?

Inspect the wedge and bronze seat if the wheel turns but flow does not shut off completely, or if leakage appears at the bonnet; the solid bronze wedge is not a routine-wear part and typically lasts many years in clean water at 200 psi.
