Nibco 3992331771 Ball Valve 1/2 Inch Lever Handle

Product Description

The NIBCO 3992331771 is a 1/2 inch bronze ball valve with a lever handle, designed for shut-off and flow-control service in plumbing and mechanical systems. Ball valves in this class provide a quarter-turn operation that allows for fast, positive shut-off with minimal pressure drop. The lever handle gives the operator a clear visual indication of valve position, open or closed. This valve is suited for licensed plumbers and pipefitters working on residential and light commercial water, hydronic, and general-purpose fluid systems.

This valve fits standard 1/2 inch pipe installations and is appropriate for use in new construction and retrofit applications. The bronze body construction makes it a common choice for potable water lines, heating and cooling distribution piping, and similar service environments where a durable, corrosion-resistant shut-off is required. It is typically installed at branch take-offs, equipment isolation points, or service locations where periodic shut-off access is needed.

Key Features

• Quarter-turn lever handle for fast shut-off and open visual confirmation
• Bronze body construction for corrosion resistance in wet service environments
• 1/2 inch pipe size fits standard residential and light commercial piping
• Full-port ball design supports low-restriction flow through the valve

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 1/2 inch pipe systems 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 requirements. Shut off the water supply and relieve system pressure before removing or installing any valve. Use appropriate thread sealant or PTFE tape on threaded connections and tighten to fitting manufacturer specifications without over-torquing the valve body. Confirm full open and full closed positions by operating the lever handle before returning the system to service.
