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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLug-style body allows end-of-line service without downstream pipe removal\u003c\/li\u003e\n\u003cli\u003eDuctile iron body and disc provide strength and impact resistance\u003c\/li\u003e\n\u003cli\u003eGrade 416 stainless steel stem for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBuna-N seat material for broad fluid compatibility\u003c\/li\u003e\n\u003cli\u003e250 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eLead-free construction for code-compliant potable water service\u003c\/li\u003e\n\u003cli\u003eMeets MSS SP-67 and U.S. Coast Guard Category A requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for installation in 2-1\/2 inch lug-pattern butterfly valve applications conforming to MSS SP-67 flange drilling patterns in commercial, industrial, and marine piping systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes.
