Nibco NJ1M00A Gate Valve 1 Inch Soldered Bronze

Product Description

The NIBCO NJ1M00A is a bronze gate valve with a rising stem design, built for 1-inch soldered-end pipe connections. It features a solid wedge disc and a bolted bonnet construction, rated at 150 pressure class. Gate valves of this type provide full-bore shutoff with minimal flow restriction when open, making them a standard choice for isolation service in water supply, HVAC hydronic, and general plumbing systems. The rising stem gives a visible indication of valve position — stem up means open, stem down means closed. Licensed plumbers and pipefitters are the primary installers of this valve.

This valve is suited for residential and light commercial plumbing and hydronic heating applications where a reliable soldered-end isolation valve is required on 1-inch copper pipe runs. It is commonly installed on branch lines, equipment isolation points, and service shutoffs in systems using copper tubing. The bolted bonnet design allows for field service if repacking is needed. Bronze construction offers corrosion resistance in potable water and hydronic service environments.

Key Features

• Rising stem design provides visual open/closed position indication

Compatibility

Designed as an OEM-style replacement or new-installation gate valve for 1-inch copper pipe systems using soldered end connections in residential and light commercial plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and drain the system fully before cutting into the line and soldering the valve into place. Allow the valve to cool completely after soldering before pressurizing the system, as heat can damage internal seals and the disc. When soldering, leave the valve in the fully open position to minimize heat transfer to the seat and disc components.
