Nibco NLH250D Wafer Butterfly Valve 2 Inches 250 Psi

Product Description

The NIBCO NLH250D is a manual wafer butterfly valve designed for flow control in piping systems where a compact, lightweight valve is required. The valve features a ductile iron body and ductile iron disc paired with a stainless steel stem, offering a durable construction suitable for demanding fluid service applications. It is rated for a maximum working pressure of 250 psi and a maximum working temperature of 180 degrees F. The Buna-N seat provides a resilient seal appropriate for a range of compatible fluid media. At 2 inches pipe size with a lever handle, this valve is a standard fit for commercial and industrial piping installations handled by licensed plumbers and pipefitters.

This valve is suited for use in commercial HVAC hydronic systems, industrial process piping, and general plumbing applications requiring manual shutoff or flow regulation at a 2 inches pipe connection. The wafer-style body installs between standard pipe flanges, keeping the overall installation footprint minimal. It meets MSS SP-67 standards and carries U.S. Coast Guard Category A approval, making it appropriate for both land-based and marine service environments. The lead-free construction meets applicable potable and non-potable water system requirements where lead-free valves are mandated.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Depressurize and drain the line fully before removing any existing valve or installing this unit. Ensure flange bolt patterns and gasket dimensions are verified against the bolt circle diameter specification before assembly. Do not exceed the rated working pressure or temperature limits during service.
