Industrial gate valve

The Milwaukee Valve 148 is a bronze gate valve with a 1-1/2 inch FNPT connection designed for water and steam lines in commercial and industrial piping systems. It meets MSS-SP-80 standards and carries a Class 125 rating for reliable shut-off service.

Thermals noise and power

The valve body withstands a maximum fluid temperature of 406 degrees Fahrenheit and handles cold water pressure up to 200 psi and working steam pressure up to 125 psi. Rising stem operation and a malleable iron hand wheel provide mechanical control without electrical power or generated noise.

Class 125 pressure rating

The Class 125 designation defines the pressure-temperature envelope that determines whether this valve suits the intended service conditions. Buyers needing higher pressure classes or different end connections must select an alternative model.

Questions about this item

How do I install the 1-1/2 inch FNPT gate valve, and what step is often missed?

Thread the valve onto the pipe using the 2 13/16 inch face-to-face length. The step often missed is applying pipe sealant to the FNPT threads before tightening to prevent leaks at the 200 psi CWP rating.

Which component of the bronze gate valve will need replacement after extended service?

The bronze wedge and bronze stem are the primary wear parts. Under normal water service at 200 psi CWP, the wedge seating surface typically requires inspection or replacement first due to erosion from flow.

What is the first pressure or temperature limit reached during sustained high-temperature steam use?

The 125 psi WSP steam rating is the first limit reached. The valve body is rated to 406 degrees F, but steam pressure must not exceed 125 psi under sustained operation per Class 125 and MSS-SP-80 standards.
