Nibco nlh100d Ductile Iron Wafer Butterfly Valve 2 in

Product Description

The NIBCO nlh100d is a 2-inch ductile iron wafer-style butterfly valve designed for flow control in commercial and industrial piping systems. It features an EPDM liner and a lever handle for manual operation. Rated at 200 CWP (cold working pressure) and pressure class 125/150, this valve is built for water and fluid service applications. NSF 61 and NSF 372 certified, it is suitable for use in potable water systems. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this type of valve in both new construction and retrofit projects.

The nlh100d wafer butterfly valve is used in residential and commercial water distribution, HVAC hydronic systems, and general industrial fluid handling. Its wafer-style body is designed to fit between standard Class 125 and Class 150 flanges, making it a compact choice where space between flanges is limited. The lever handle allows for quick quarter-turn shutoff, which suits applications requiring frequent manual isolation or throttling.

Key Features

• Ductile iron body construction for strength and durability in pressurized fluid service
• EPDM liner provides a resilient seat suitable for water and mildly corrosive media
• Lever handle enables quarter-turn manual operation for fast shutoff
• Rated 200 CWP for reliable performance in standard pressure applications
• NSF 61 and NSF 372 certified for potable water system use
• Wafer-style body fits between Class 125 and Class 150 flanges without additional space requirements

Compatibility

Designed as an OEM-style replacement or new-installation wafer butterfly valve for Class 125 and Class 150 flanged piping systems in commercial and industrial water service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local mechanical codes. Isolate and depressurize the piping system fully before installing or servicing this valve. Ensure flange faces are clean and properly aligned before torquing flange bolts to the specifications listed in the system design documents. Do not use this valve for throttling service at pressures or temperatures outside its published ratings.
