Nibco NLJ120L Wafer Butterfly Valve 8 Inch Lever Handle

Product Description

The NIBCO NLJ120L is a manual wafer-style butterfly valve designed for 8-inch pipe systems. It controls flow in commercial and industrial piping applications using a lever handle for quick, quarter-turn operation. The body is constructed from cast iron, the disc from ductile iron, and the stem from stainless steel. The seat is made from EPDM (Ethylene Propylene Diene Monomer), providing resistance to water, steam, and many chemical media. This valve is installed by licensed plumbers and pipefitters in a wide range of fluid-handling systems.

The NLJ120L fits between flanges in a wafer-style mounting configuration, making it a compact and cost-effective choice for flow isolation or throttling on 8-inch lines. It is commonly used in commercial HVAC hydronic systems, industrial process piping, and water distribution applications. The lever handle allows straightforward open and close operation without the need for an actuator, making it well suited for manual service points and maintenance isolation.

Key Features

• Wafer-style body mounts between flanges for compact installation on 8-inch pipe
• Cast iron body provides durability in commercial and light industrial service
• Ductile iron disc offers improved impact resistance compared to standard cast iron
• Stainless steel stem resists corrosion in wet service environments
• EPDM seat material is compatible with water, mild chemicals, and HVAC hydronic media
• Lever handle enables fast quarter-turn operation without power or an actuator

Compatibility

Designed as an OEM-style wafer butterfly valve for use on 8-inch pipe flanged systems in commercial HVAC, plumbing, and industrial piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Shut off and depressurize the system fully before installing or servicing the valve. Wafer valves must be properly centered between flanges using appropriate flange bolts and gaskets per applicable IPC and ASME standards. Do not install with the disc in a partially open position during initial flange tightening, as this can damage the seat.
