Nibco NL0Z00A Gate Valve 1 Inch Threaded Bronze 125 Class

Product Description

The NIBCO NL0Z00A is a rising stem gate valve designed for full-bore isolation service in plumbing, hydronic heating, and industrial piping systems. The bronze body resists corrosion in water and low-pressure steam applications. A solid wedge disc provides positive shutoff, while the union bonnet allows in-line packing maintenance without removing the valve from the pipeline. Rated at pressure class 125, this valve is threaded for 1-inch pipe connections. Licensed plumbers and pipefitters install this valve in both commercial and residential mechanical systems.

This gate valve is suited for residential and light commercial water distribution, hydronic heating loops, and general-purpose fluid service where a full-flow, low-pressure-drop isolation point is required. The threaded end connection makes it compatible with standard 1-inch NPT piping assemblies. The rising stem design provides a clear visual indication of valve position, a useful feature in mechanical rooms and utility spaces where quick status checks are important during service calls.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME standards. Shut off and depressurize the system completely before installing or removing the valve. Use appropriate pipe thread sealant or PTFE tape on the threaded connections. Gate valves should be installed in the fully open or fully closed position and are not intended for throttling service.
