Milwaukee Valve 3/4" Solder Low Lead Brass Swing Check Valve 968000034

Brass swing check valve

The Milwaukee Valve 968000034 is a 3/4-inch low-lead brass swing check valve designed for potable water lines. It uses a sweat-by-sweat connection for permanent copper pipe installations and allows full flow in one direction while preventing backflow. The valve operates horizontally or vertically and handles water pressures up to 200 psi at 150 degrees Fahrenheit. It suits residential and light commercial plumbing systems requiring lead-free compliance.

Inline installation and orientation

This inline valve fits directly into 3/4-inch copper tubing using solder joints, so no threaded adapters or flanges are required. The swing mechanism opens at a cracking pressure of .1 psi and delivers a flow rate of 18 gallons per minute with a metal seat seal. Brass body and seal materials withstand temperatures from -20 to 150 degrees Fahrenheit. The compact swing design frees up space compared to lift-check alternatives and needs no external power or control wiring.

Replaces worn or non-compliant checks

The valve replaces older swing checks that leak, restrict flow, or contain higher lead alloys no longer permitted for drinking water. The jump is worth it when a system demands full 18 gpm capacity, low cracking pressure, and horizontal or vertical mounting flexibility. It is not suited for steam service, applications above 200 psi water pressure, or pipes sized other than 3/4 inch. Builders needing flanged, threaded, or larger-diameter connections must select a different model.
