  • TypeOther
  • Reliable flow control for gas, oil or water systems
  • Class 125 bronze construction rated to 200 psi operating pressure

2-1/2" Gate Valve for Gas Oil Water Systems

The Milwaukee Valve 148 is a bronze gate valve designed to control the flow of gas, oil, or water in commercial and industrial piping. Its 2-1/2 inch FNPT connection integrates directly into female NPT threads without adapters. The solid bronze wedge and rising stem provide reliable shut-off for plumbing and mechanical contractors.

Bronze Construction Handles 200 psi Cold Working

The all-bronze body, bonnet, stem, wedge, seat, and seal resist corrosion across the listed media. Rated for 200 psi maximum operating pressure and 125 psi steam pressure, the valve suits typical hydronic and low-pressure steam lines. The screw-in bonnet and wheel handle allow straightforward manual operation with minimal packing leakage.

337 Cv Rating Replaces Smaller Gate Valves

A coefficient of volume of 337 indicates high flow capacity with low pressure drop when fully open. Specify this model when upgrading from smaller gate valves that restrict flow in 2-1/2 inch pipe networks. The rising stem design also replaces non-rising alternatives where visual indication of valve position is required.

Questions about this item

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

Thread the valve onto the male NPT pipe using pipe sealant on the threads; the step often missed is tightening with a wrench on the valve body flats only, never on the handwheel or stem, to avoid damaging the rising-stem mechanism.

What maintenance will the bronze gate valve need over time?

Periodically operate the handwheel through a full open-close cycle to prevent the solid bronze wedge from seizing in the bronze seats, and inspect the screw-in bonnet joint for any weeping that would indicate the bronze-to-bronze seal needs re-torquing or fresh thread sealant.

At what pressure limit does the Class 125 valve reach its rating first under sustained steam service?

The valve is rated for 125 psi maximum steam pressure, which is lower than its 200 psi cold working pressure, so the steam rating becomes the governing limit during prolonged high-temperature use.
