1/2" Bronze Gate Valve Class 125

This 1/2-inch gate valve from Milwaukee Valve handles gas, oil and water in residential and light-commercial plumbing. The bronze body, solid bronze wedge and bronze seat resist corrosion across a range of fluids. Rising-stem design with a wheel handle gives clear visual indication of open or closed position. Female NPT threads simplify installation on standard pipe.

Sustained pressure and temperature rating

The valve is rated for 200 psi maximum operating pressure and 125 psi steam service, making it suitable for continuous duty on low-pressure steam lines and pumped water systems. A Cv of 17.6 provides ample flow capacity for 1/2-inch supply branches without excessive pressure drop. Bronze stem and screw-in bonnet maintain seal integrity through repeated thermal cycles.

Replaces worn bronze gate valves

Swapping out a leaking or seized bronze gate valve of the same size and pressure class restores positive shut-off without re-piping. The jump is worth it when the existing valve no longer seals at 200 psi cold working pressure or when stem threads are stripped. Not suited for applications requiring throttling control or quarter-turn operation.

Questions about this item

How much heat does the 1/2" gate valve generate when it runs all day?

The bronze body and bronze stem do not generate measurable heat during continuous operation; the valve simply controls flow of gas, oil or water without a motor or electrical load.

What piping must I already have to install this valve?

You need a 1/2" female NPT threaded connection on each side of the line so the valve can screw directly into the existing pipework.

Will the Class 125 bronze valve work with older steel pipe threads I have in place?

Yes, the 1/2" female NPT threads mate with standard NPT male threads on legacy steel, copper or plastic piping without adapters.
