Nibco NL3W004 Bronze Globe Valve 1/4 Inch Threaded 600 Psi

Product Description

The NIBCO NL3W004 is a bronze integral globe valve designed for precise flow control in plumbing and industrial piping systems. Built with a bronze body and bronze disc, it features threaded end connections sized at 1/4 inch pipe and a union bonnet design for easy in-line maintenance without removing the valve from the line. Rated at 600 psi WOG (water, oil, gas) and 300 psi WSP (working steam pressure), this Class 300 valve suits demanding service environments where reliable shutoff and throttling are required. A handwheel handle provides positive, repeatable manual operation. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This globe valve is suited for residential and light commercial plumbing, hydronic heating systems, compressed air lines, steam service within its rated pressure, and general industrial fluid handling. The 1/4 inch threaded connection makes it a direct fit in small-bore piping runs where precise flow regulation is needed. Its compact size and union bonnet configuration are common in boiler rooms, mechanical rooms, and equipment isolation applications where service access is a priority.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off system pressure and drain the line before removing or installing any valve. Apply thread sealant or PTFE tape to male threads in accordance with IPC guidelines, and verify that the valve flow direction arrow aligns with system flow. Do not exceed the rated WOG or WSP pressure for the intended service medium.
