Nibco NLH150F 3 Inch Wafer Butterfly Valve Lever Handle

Product Description

The NIBCO NLH150F is a manual wafer-style butterfly valve designed for flow control in piping systems where space between pipe flanges is limited. Sized for 3-inch pipe and operated by a lever handle, this valve features a ductile iron body, an aluminum bronze disc, and a stainless steel stem rated at material grade 416. The Buna-N seat provides a reliable shutoff and is rated for service up to 180 degrees F at pressures up to 200 psi. This valve is lead free and meets MSS SP-67 and U.S. Coast Guard Category A requirements. It is installed by licensed plumbers, pipefitters, and mechanical contractors in commercial and industrial piping applications.

The NLH150F is suited for water and general fluid service in commercial mechanical systems, HVAC piping, and marine applications. Its wafer body style fits between standard ANSI flanges without requiring a full-flange valve body, making it practical for retrofit and new-construction installations where face-to-face clearance is a concern. The lever handle allows for quick quarter-turn open and close operation, which is standard in balancing and isolation service.

Key Features

• Wafer body fits between ANSI flanges for compact face-to-face installation
• Ductile iron body provides durability in demanding commercial and industrial service
• Aluminum bronze disc (material grades 954 and 955) resists corrosion in water service
• Stainless steel stem (grade 416) for reliable operation and corrosion resistance
• Buna-N seat rated to 180 degrees F and 200 psi maximum working pressure
• Lead free construction meets applicable potable water and plumbing code requirements
• Complies with MSS SP-67 and U.S. Coast Guard Category A standards

Compatibility

Designed as an OEM-style wafer butterfly valve for 3-inch ANSI-flanged piping systems in commercial plumbing, HVAC, and marine mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the piping system completely before installing or removing the valve. Confirm flange bolt circle and face-to-face dimensions are compatible with the existing piping before installation. The lever handle requires clearance for a full 90-degree rotation — verify access before final positioning in the line.
