Nibco NLJ160K Wafer Butterfly Valve 6 Inch Lever Handle

Product Description

The NIBCO NLJ160K is a manual wafer-style butterfly valve designed for 6-inch pipe systems. It features a cast iron body, ductile iron disc, and stainless steel stem, paired with a Buna-N seat for reliable shutoff performance. The lever handle provides simple, direct quarter-turn operation without the need for a gear actuator. This valve is sized and built for use in commercial and industrial fluid handling systems where a lightweight, compact wafer configuration is required between flanges. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers.

This valve is suited for use in closed-loop hydronic systems, cooling water lines, process piping, and general service fluid applications where a 6-inch wafer-style butterfly valve with manual lever control is specified. The Buna-N seat material is compatible with water and many common non-aggressive fluids. The wafer body profile keeps installation compact and fits between standard pipe flanges without a full-lug body.

Key Features

• 6-inch pipe size with wafer-style body for compact flange-to-flange installation
• Cast iron body provides durability in commercial and industrial piping environments
• Ductile iron disc offers strength and resistance to mechanical stress
• Stainless steel stem resists corrosion in wet service conditions
• Buna-N seat material suitable for water and compatible fluid service
• Lever handle delivers direct quarter-turn manual operation

Compatibility

Designed as a wafer-style butterfly valve for use between standard pipe flanges on 6-inch piping systems in commercial and industrial fluid handling applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Depressurize and drain the piping system fully before removing or installing any valve. Confirm flange bolt pattern and face-to-face dimensions are compatible with the wafer body profile before torquing fasteners. Follow applicable IPC and local mechanical code requirements for valve placement, support, and service accessibility.
