Nibco NLG250E Lug Butterfly Valve 2-1/2 Inch 250 Psi

Product Description

The NIBCO NLG250E is a manual lug-style butterfly valve designed for flow control in commercial and industrial piping systems. Built with a ductile iron body and ductile iron disc, this valve is engineered for durability under pressure. The stainless steel stem (material grade 416) resists corrosion, and the Buna-N seat provides a reliable seal across a wide range of fluid service applications. Rated to 250 psi maximum working pressure and 180 degrees F maximum working temperature, the NLG250E handles demanding service conditions. A lever handle allows for quick quarter-turn manual actuation. The lug-style body enables end-of-line service or in-line installation without removing downstream piping.

This valve is sized for 2-1/2 inch pipe and is suited for use in commercial HVAC systems, industrial process lines, water distribution, and marine applications. The U.S. Coast Guard Category A rating makes it appropriate for shipboard use. Licensed plumbers and pipefitters typically install this valve in systems where manual shutoff or flow isolation is required. It complies with MSS SP-67 for butterfly valves and carries MSS SP-25 markings. Lead-free construction meets applicable potable water regulations where required by code.
