Nibco NL3MN04 Bronze Globe Valve 0.25 in Threaded 400 Psi

Product Description

The NIBCO NL3MN04 is a bronze, renewable full plug disc globe valve designed for flow regulation and shutoff in plumbing and piping systems. It features a union bonnet for easy in-line maintenance and alloy-threaded disc construction that allows disc replacement without removing the valve body from the line. Rated at 400 psi WOG (water, oil, gas) and 200 psi WSP (working steam pressure), this valve is built for demanding service in both liquid and steam applications. The 0.25 inch pipe size and threaded end connections make it a straightforward installation for licensed plumbers and pipefitters working on residential or light commercial systems.

The NL3MN04 is suited for use in water, oil, gas, and steam service lines where precise flow control or positive shutoff is required. Its compact 0.25 inch size fits tight spaces common in equipment rooms, boiler rooms, and mechanical chases. The threaded ends allow direct connection to standard NPT piping without the need for flanges or special adapters. Plumbers and mechanical contractors typically install this valve during new construction or as a replacement in existing systems where a union bonnet design is specified for serviceability.

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 completely before removing any existing valve or installing this unit. Use thread sealant or PTFE tape rated for the service medium on all NPT connections. Verify that system operating pressure does not exceed the valve pressure class rating for the fluid and temperature in service.
