Nibco nl3w00b Bronze Globe Valve 1-1/4 in CL300

Product Description

The NIBCO nl3w00b is a 1-1/4 inch bronze threaded globe valve designed for flow regulation in commercial and industrial piping systems. It features a union bonnet construction rated to Class 300 with a cold working pressure (CWP) of 600 psi. The valve is rated for service up to 300 degrees F on steam and 421 degrees F on non-steam applications. Female pipe thread (FPT) end connections make it compatible with standard threaded pipe assemblies. Plumbers, pipefitters, and mechanical contractors install this valve where precise throttling control is required.

This valve is suited for commercial plumbing, heating, and industrial process piping where a threaded globe-style valve is specified. The bronze body handles water, steam, and other compatible fluids within the rated pressure and temperature limits. The union bonnet design allows internal inspection and maintenance without removing the valve body from the line, reducing downtime in operating systems.

Key Features

• 1-1/4 inch female pipe thread (FPT) end connections for standard threaded pipe installation
• Union bonnet construction allows in-line servicing and disc replacement
• Class 300 pressure rating with 600 psi cold working pressure
• Temperature rated to 300 degrees F steam service and 421 degrees F non-steam service

Compatibility

Designed as an OEM-style replacement or new-installation globe valve for 1-1/4 inch threaded piping systems requiring Class 300 bronze valve construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes, including IPC and ASME B31 piping standards. Shut off and depressurize the system completely before installing or servicing the valve. Apply appropriate thread sealant or PTFE tape to FPT connections and tighten to pipe manufacturer specifications. Do not exceed the rated CWP or temperature limits for the service fluid.
