Nibco NLH150L Wafer Butterfly Valve 8 Inch Lever

Product Description

The NIBCO NLH150L is a manual wafer-style butterfly valve designed for 8-inch pipe systems. It features a ductile iron body, an aluminum bronze disc, and a stainless steel stem, making it a durable choice for flow control in commercial and industrial piping applications. The lever handle provides direct, manual quarter-turn operation for quick open and close cycles. The Buna-N seat delivers reliable sealing across a broad range of fluid service conditions. This valve is typically installed by licensed plumbers or pipefitters working on medium to large-diameter piping systems.

The NLH150L wafer butterfly valve is suited for 8-inch pipe installations in commercial HVAC hydronic systems, industrial process piping, and water distribution lines. Its wafer-style body fits between standard pipe flanges, minimizing face-to-face installation length and reducing overall system weight compared to lug or flanged body alternatives. The lever handle configuration makes it well suited for applications where frequent manual actuation is required and space allows for handle swing clearance.

Key Features

• Ductile iron body for strength and corrosion resistance in demanding service environments

• Stainless steel stem provides corrosion resistance and long service life
• Buna-N seat material for reliable sealing across a wide range of compatible fluids
• Wafer-style body fits between flanges for compact face-to-face installation
• Lever handle enables fast quarter-turn manual operation

Compatibility

Designed as an OEM-style wafer butterfly valve for 8-inch pipe systems utilizing standard flange bolt patterns in commercial and industrial piping installations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing codes. Depressurize and drain the piping system fully before installing or servicing this valve. Verify flange bolt pattern and gasket compatibility before final torque of flange hardware. Confirm that the disc swing path is clear of pipe interferences before mounting between flanges.
