Product Identity

The Milwaukee Valve UP668 is a 1-1/2 inch brass gate valve with a sweat connection designed for water supply lines. It features a solid forged brass wedge, brass stem, and a screw-in bonnet operated by a wheel handle. The valve carries a 200 psi operating pressure rating and a Cv of 135 for flow capacity.

Suitable Installations

This valve suits plumbing systems requiring a full-port shut-off for water where a sweat joint is specified and 200 psi pressure class is sufficient. Installers needing a rising stem, threaded or flanged ends, or a higher pressure rating for steam service should look at alternative valve types.

Decisive Specification

The sweat connection type determines whether this valve fits the piping assembly; it requires copper tubing and soldering tools for installation. Verify that the 1-1/2 inch nominal size and 200 psi water rating match the system design before purchasing.

Questions about this item

What does the 135 Cv rating mean for actual water flow?

A Cv of 135 indicates the valve allows 135 US gallons per minute of water at a 1 psi pressure drop, so it supports high-volume supply lines with minimal restriction.

How does the sweat connection work with copper pipe?

The sweat end is sized for 1-1/2 inch copper tubing; you clean, flux, insert the tube, and solder the joint for a permanent leak-free seal.

What clearance is needed for the wheel handle and bonnet?

The non-rising stem keeps the wheel at a fixed height, so you only need room above the bonnet for hand operation and the screw-in bonnet for occasional packing adjustments.
