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.

Questions about this item
What pipe size and thread type must the existing plumbing have to connect this 1-1/2" FNPT gate valve?
The plumbing needs a 1-1/2 inch female NPT thread to match the valve's FNPT connections.
Will the 300 psi CWP rating and bronze body handle the same pressures as older Class 150 bronze valves already in the system?
Yes, the 300 psi cold water pressure rating and bronze construction match typical Class 150 specifications for compatible service.
How can I confirm the rising stem and hand wheel operate correctly after installation?
Turn the hand wheel; the stem should rise visibly as the bronze wedge lifts, showing the gate is opening.
