Nibco NLJ160F Wafer Butterfly Valve 3 Inch 200 Psi

Product Description

The NIBCO NLJ160F is a manual wafer-style butterfly valve designed for flow control in industrial and commercial piping systems. Built with a cast iron body and ductile iron disc, it delivers durable shutoff performance at working pressures up to 200 psi and temperatures up to 180 degrees F. The stainless steel stem resists corrosion in demanding service environments. A Buna-N seat provides a reliable seal. The lever handle allows quick quarter-turn operation, making it a practical choice for maintenance and isolation applications. Licensed plumbers and pipefitters are the typical installers for this type of valve.

This valve is sized for 3-inch pipe and uses a wafer-style body that fits between standard pipe flanges, keeping the installation compact and reducing overall spool piece length. It is suited for water, mild chemical service, and HVAC hydronic systems where a low-profile shutoff valve is needed. The lever handle design makes it well suited for accessible, above-grade service points where frequent cycling or balancing is required. It meets MSS SP-25 marking standards, API 609, and MSS SP-67 performance requirements.

Key Features

• Cast iron body provides structural durability in commercial and light industrial service
• Ductile iron disc offers strength and impact resistance under pressure cycling
• Stainless steel stem resists corrosion and extends service life
• Buna-N seat delivers a tight shutoff seal compatible with water and many mild fluids
• Quarter-turn lever handle enables fast open and close operation
• Meets API 609 and MSS SP-67 standards for butterfly valve performance and markings

Compatibility

Designed as an OEM-style wafer butterfly valve for 3-inch flanged piping systems in commercial HVAC, plumbing, and light industrial applications where cast iron body construction and lever-operated shutoff are specified.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. De-pressurize and drain the piping system completely before removing or installing the valve. Wafer-style valves must be centered carefully between mating flanges and torqued evenly in a cross pattern to avoid seat distortion and leakage. Verify flange bolt circle and face-to-face dimensions are compatible with the existing piping before installation.
