Nibco NLJ120K Wafer Butterfly Valve 6 Inch Lever Handle

Product Description

The NIBCO NLJ120K is a manual wafer-style butterfly valve designed for flow control in commercial and industrial piping systems. Built around a 6-inch pipe size, it features a cast iron body, ductile iron disc, and stainless steel stem. The lever handle provides direct quarter-turn operation for quick open and close actuation. An EPDM seat provides a resilient seal compatible with a range of fluid media. This valve is a wafer pattern, meaning it fits between two flanges without its own flange faces, keeping the installed footprint compact. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers for this type of valve.

The NLJ120K is suited for commercial plumbing, HVAC hydronic systems, irrigation, and general industrial fluid handling where a reliable shutoff or throttling valve is needed at a 6-inch pipe size. Its lever handle operation makes it appropriate for applications requiring frequent manual actuation. The wafer body style allows installation in tight spaces between standard ANSI flanges. This valve is commonly found in mechanical rooms, pump stations, and water distribution headers.

Key Features

• Wafer-pattern body fits between standard ANSI flanges for a compact installation footprint
• Cast iron body provides durability in commercial and light industrial environments
• Ductile iron disc offers improved toughness and impact resistance over standard gray iron
• Stainless steel stem resists corrosion and provides reliable torsional strength during actuation
• EPDM seat delivers a resilient, low-leak seal compatible with water, mild chemicals, and steam service within rated limits
• Lever handle enables fast quarter-turn open and close operation without additional actuator hardware

Compatibility

Designed as an OEM-style wafer butterfly valve for use with 6-inch pipe in standard ANSI-flanged commercial plumbing and hydronic piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the system fully before removing any existing valve or installing this unit. Verify that the flange bolt pattern, pressure rating, and seat material are compatible with the service fluid and operating conditions before installation. Do not exceed the rated pressure or temperature limits for the EPDM seat material.
