It controls flow in commercial and industrial piping applications using a lever handle for quick, quarter-turn operation. The body is constructed from cast iron, the disc from ductile iron, and the stem from stainless steel. The seat is made from EPDM (Ethylene Propylene Diene Monomer), providing resistance to water, steam, and many chemical media. This valve is installed by licensed plumbers and pipefitters in a wide range of fluid-handling systems.\u003c\/p\u003e\u003cp\u003eThe NLJ120L fits between flanges in a wafer-style mounting configuration, making it a compact and cost-effective choice for flow isolation or throttling on 8-inch lines. It is commonly used in commercial HVAC hydronic systems, industrial process piping, and water distribution applications. The lever handle allows straightforward open and close operation without the need for an actuator, making it well suited for manual service points and maintenance isolation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWafer-style body mounts between flanges for compact installation on 8-inch pipe\u003c\/li\u003e\n\u003cli\u003eCast iron body provides durability in commercial and light industrial service\u003c\/li\u003e\n\u003cli\u003eDuctile iron disc offers improved impact resistance compared to standard cast iron\u003c\/li\u003e\n\u003cli\u003eStainless steel stem resists corrosion in wet service environments\u003c\/li\u003e\n\u003cli\u003eEPDM seat material is compatible with water, mild chemicals, and HVAC hydronic media\u003c\/li\u003e\n\u003cli\u003eLever handle enables fast quarter-turn operation without power or an actuator\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wafer butterfly valve for use on 8-inch pipe flanged systems in commercial HVAC, plumbing, and industrial piping applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter. Shut off and depressurize the system fully before installing or servicing the valve. Wafer valves must be properly centered between flanges using appropriate flange bolts and gaskets per applicable IPC and ASME standards. Do not install with the disc in a partially open position during initial flange tightening, as this can damage the seat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Wafer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Material\u003c\/strong\u003e: Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: EPDM (Ethylene Propylene Diene Monomer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 29 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NIBCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: NLJ120L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51541407465778,"sku":"NLJ120L","price":452.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2add512f191974b36ba03c130f2076c3.jpg?v=1785875083","url":"https:\/\/voomisupply.com\/products\/nibco-nlj120l-wafer-butterfly-valve-8-inch-lever-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
