Nibco NLJ160E Wafer Butterfly Valve 2-1/2 Inch Lever Handle

Product Description

The NIBCO NLJ160E is a manual wafer-style butterfly valve designed for 2-1/2 inch pipe systems. It provides reliable on/off flow control in a compact, wafer body that fits between standard flanges without the bulk of a lug-style valve. The body is cast iron, the disc is ductile iron, and the stem is stainless steel — a material combination suited for moderate-duty commercial and industrial piping applications. A lever handle allows quick quarter-turn operation without additional actuator hardware. Licensed plumbers and pipefitters are the typical installers in hydronic, HVAC, and general process piping systems.

This valve is used in 2-1/2 inch pipe installations where a low-profile shutoff or isolation point is needed. Common applications include hydronic heating and cooling systems, chilled water distribution, condenser water loops, and light industrial fluid handling. The wafer configuration makes it well-suited for tight mechanical room installations where flange-to-flange space is limited. The Buna-N seat material provides compatibility with water, air, and a range of mild fluids encountered in building mechanical systems.

Key Features

• Wafer-style body fits between standard flanges for compact installation
• Cast iron body construction for moderate-duty commercial service
• Ductile iron disc offers greater toughness and impact resistance compared to standard cast iron
• Stainless steel stem resists corrosion in wet piping environments
• Buna-N seat material compatible with water, air, and mild process fluids
• Lever handle delivers fast quarter-turn open/close operation

Compatibility

Designed as an OEM-style wafer butterfly valve replacement or new installation component for 2-1/2 inch pipe systems using standard flange bolt patterns in commercial mechanical and light industrial piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B31 piping standards. Isolate and depressurize the system fully before removing or installing any valve. Ensure proper flange alignment and bolt pattern match before torquing flange hardware. Verify fluid compatibility with the Buna-N seat before placing the valve in service with any fluid other than water or air.
