Milwaukee Valve 1150 1-1/2 Gate Valve Class 150

1-1/2 Inch Bronze Gate Valve

This Milwaukee Valve 1150 is a Class 150 bronze gate valve with FNPT connections for 1-1/2 inch pipe. It handles cold water up to 300 psi and saturated steam up to 150 psi. The rising stem design and threaded bonnet provide reliable shut-off for plumbing and heating systems. Malleable iron hand wheel allows manual operation.

Suited for residential and light commercial piping

This valve fits installations requiring bronze construction and Class 150 pressure ratings with threaded ends. It is not for applications needing flanged connections or higher pressure classes beyond 300 psi CWP. Buyers who want a non-rising stem or different body material should look at other valve types. Systems requiring automated actuation need a different configuration.

300 psi cold water and 150 psi steam capacity

The valve comfortably handles water pressure up to 300 psi and steam pressure up to 150 psi at temperatures reaching 406 degrees Fahrenheit. It runs out of headroom above these pressure and temperature limits. The 1-1/2 inch pipe size and FNPT threading define the flow capacity for this specific model. MSS-SP-80 compliance confirms the design standard.
