Nibco NL3MN0C Bronze Globe Valve 1-1/2 in Threaded

Product Description

The NIBCO NL3MN0C is a bronze renewable full plug disc globe valve designed for fluid isolation and flow control in commercial and industrial piping systems. Built with a union bonnet for easy in-line maintenance, this valve accepts 1-1/2 inch threaded pipe connections and is rated at 400 psi WOG (water, oil, gas) and 200 psi WSP (working steam pressure), placing it in Class 200 service. The renewable full plug disc design allows the seating surface to be replaced without removing the valve body from the line. Licensed plumbers and pipefitters install this type of valve in mechanical rooms, boiler rooms, and process piping where reliable shutoff and long service life are required.

This globe valve is suited for residential and commercial plumbing, steam, and general-purpose piping applications where threaded connections are standard. The 1-1/2 inch pipe size fits common branch and main line configurations in hydronic heating systems, steam distribution, water service, and light industrial process lines. Its bronze construction provides corrosion resistance in wet service environments. The alloy-threaded disc contributes to durability under repeated cycling and high-pressure conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local mechanical codes. Shut off and depressurize the line completely before installing or servicing this valve. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Flow direction through a globe valve is critical — observe the directional arrow cast on the valve body during installation.
