Gate Valve for Water Systems

The Milwaukee Valve UP668 is a 2-inch gate valve designed for water supply lines in residential and commercial plumbing. Its low-lead brass construction meets safety standards for potable water applications. The sweat connection allows for a permanent soldered joint on copper piping. It is intended for installers who need a reliable shut-off valve for wet systems.

Non-Rising Stem and Solid Wedge

The valve features a non-rising stem with a wheel handle, so the handle position does not indicate open or closed status but requires less vertical clearance above the pipe. A screw-in bonnet secures the internal components and allows access for maintenance. The solid forged brass wedge and brass seats provide a tight seal against the 200 psi operating pressure rating. These components work together to deliver a Cv of 230 for efficient flow.

High-Capacity Shut-Off for 2-Inch Lines

This valve comfortably handles water service up to its 200 psi pressure limit with a high flow coefficient that minimises restriction in 2-inch copper systems. It is not rated for steam service, so it cannot be used in heating loops or process steam lines. The sweat ends require copper pipe and soldering skill, ruling out threaded or press-fit installations. Buyers needing a rising stem for visual position indication or a valve rated for steam will need a different design.

Questions about this item

Will the brass stem or seat need periodic replacement under normal water service?

The stem and seat are both brass, so they resist corrosion; replacement is only needed if debris scores the sealing surfaces during operation.

What pressure limit governs continuous duty on this 2-inch gate valve?

The valve is rated for a maximum operating pressure of 200 psi, which is the limiting figure for sustained use.

Does the valve generate noticeable heat or noise when left fully open all day?

With a Cv of 230 the flow passage is unrestricted, so the valve adds negligible turbulence, heat or noise during continuous operation.
