Nibco NL3X00B Bronze Globe Valve 1-1/4 Inch Threaded

Product Description

The NIBCO NL3X00B is a bronze integral globe valve designed for precise flow control in steam, water, oil, and gas piping systems. It features a 1-1/4 inch pipe connection with threaded ends and a union bonnet for easy in-line maintenance without removing the valve body from the line. The PTFE disc provides a reliable, corrosion-resistant seat seal. Rated at 600 psi WOG (water, oil, gas) and 300 psi WSP (working steam pressure), this Class 300 valve is built for demanding commercial and industrial service. A handwheel handle gives the installer precise throttling control. Licensed plumbers and pipefitters are the typical installers.

The NL3X00B is suited for use in commercial and industrial piping systems where throttling or shutoff of steam, water, oil, or gas is required. The threaded end connections make it compatible with standard NPT pipe in new construction and retrofit applications. The union bonnet design simplifies inspection and repacking in active systems, reducing downtime during maintenance. This valve is commonly installed in mechanical rooms, boiler rooms, and process piping where Class 300 rated components are specified.

Key Features

Compatibility

Designed as an OEM-style replacement or new-install globe valve for 1-1/4 inch NPT threaded piping systems rated to Class 300 service in commercial and industrial plumbing and steam applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. Depressurize and drain the line fully before installing or servicing the valve. Apply thread sealant or PTFE tape to NPT threads per standard practice. The union bonnet allows packing replacement without removing the valve body, but system pressure must still be fully relieved before opening the bonnet.
