Milwaukee Valve 1150 1-1/4 Gate Valve Class 150

1-1/4" Class 150 Bronze Gate Valve

The Milwaukee Valve 1150 is a rising-stem gate valve built from bronze with a threaded bonnet and bronze wedge. It connects via 1-1/4" FNPT threads and is rated for 300 psi cold water pressure and 150 psi saturated steam. A malleable iron hand wheel operates the bronze stem for positive shut-off in residential or light commercial plumbing.

Threaded FNPT Connection Fits Standard Piping

The valve installs directly onto 1-1/4" female NPT pipe ends without flanges or solder joints. Its 2 25/32 inch face-to-face dimension keeps the installed length compact, while the rising stem provides clear visual indication of gate position. The threaded bonnet allows straightforward access to the seat and wedge for inspection or maintenance.

Replaces Worn Gate Valves In Existing Lines

This unit suits repairs where a bronze Class 150 gate valve has failed or leaks past the seat. It matches the pressure and temperature envelope of the original MSS-SP-80 specification, so the swap restores rated performance without re-piping. Installers needing a ball valve or a higher-pressure rating should select a different valve type.
