Nibco NLG250F Lug Butterfly Valve 3 Inch 250 Psi

Product Description

The NIBCO NLG250F 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 handles 3-inch pipe and operates via a lever handle for quick, positive shutoff. The stainless steel stem (Grade 416) resists corrosion in demanding service environments. Rated for a maximum working pressure of 250 psi and a maximum working temperature of 180 degrees F, the NLG250F is suited for water, HVAC hydronic systems, and general fluid service applications. It carries a lead-free designation, supporting compliance where lead-free materials are required.

The NLG250F is used in commercial HVAC hydronic piping, industrial process lines, and mechanical room installations where a compact, lever-actuated shutoff is needed at a 3-inch pipe size. The lug-style body allows end-of-line service and valve removal without disturbing the downstream piping. Licensed pipefitters and mechanical contractors typically specify lug butterfly valves in situations where isolation without full system shutdown is a priority.
