Nibco NLH250J Wafer Butterfly Valve 5 Inch 250 Psi

Product Description

The NIBCO NLH250J is a manual wafer butterfly valve designed for 5-inch pipe installations in commercial and industrial piping systems. It features a ductile iron body and disc, a stainless steel stem with a material grade of 416, and a Buna-N seat. The lever handle provides direct manual operation without the need for actuators or additional controls. Rated to 250 psi maximum working pressure and up to 180 degrees F, this valve handles a broad range of fluid control applications. It meets MSS SP-67 requirements and carries U.S. Coast Guard Category A approval, making it suitable for marine and regulated installations. The valve is lead free, meeting current standards for potable and process water systems.

The NLH250J is suited for commercial HVAC, industrial process piping, marine, and general fluid handling applications where a compact, wafer-style valve is required between flanges. The wafer design reduces face-to-face dimension compared to lug-style valves, keeping installation simple in tight piping runs. Licensed plumbers and pipefitters typically install this valve in both new construction and retrofit projects. Its lever handle allows quick quarter-turn shutoff, making it a practical choice for isolation service on 5-inch lines.

Key Features

• Lever handle delivers fast quarter-turn manual operation
• Rated to 250 psi maximum working pressure
• Lead free construction meets current regulatory requirements
• Meets MSS SP-67 and carries U.S. Coast Guard Category A approval

Compatibility

Designed as an OEM-style wafer butterfly valve for use between standard ANSI flanges on 5-inch pipe systems in commercial, industrial, and marine fluid handling applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and ASME piping standards. Isolate and depressurize the line completely before installing or servicing the valve. The wafer body must be centered carefully between mating flanges with appropriate flange bolts and gaskets to ensure a leak-free seal. Confirm the valve disc is in the fully open position during installation to prevent disc damage during bolt tightening.
