Built with a cast iron body, ductile iron disc, and stainless steel stem, this valve handles demanding service conditions while keeping weight manageable at 10.8 pounds. The lever handle allows quick quarter-turn operation for open and shut control without the need for tools or actuators. Rated to 200 psi maximum working pressure and 250 degrees F maximum working temperature, the NLJ120H suits a wide range of liquid service applications where reliable shutoff or throttling is required.\u003c\/p\u003e\u003cp\u003eThis valve is suited for 4-inch pipe installations in commercial HVAC, plumbing, and industrial process piping systems. The wafer-style body fits between standard pipe flanges, keeping the installation footprint compact and reducing overall system weight compared to lug-style alternatives. The ethylene propylene diene monomer (EPDM) seat material performs well in hot water and many water-based fluid services. Licensed plumbers, pipefitters, and mechanical contractors typically specify this valve for hydronic heating and cooling systems, chilled water lines, and general water distribution applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron body construction for durability in commercial and industrial service\u003c\/li\u003e\n\u003cli\u003eDuctile iron disc provides strength and corrosion resistance in water service\u003c\/li\u003e\n\u003cli\u003eStainless steel stem resists corrosion and supports long service life\u003c\/li\u003e\n\u003cli\u003eEPDM seat rated for hot water and water-based fluid compatibility\u003c\/li\u003e\n\u003cli\u003e200 psi maximum working pressure for high-demand piping systems\u003c\/li\u003e\n\u003cli\u003eLever handle delivers fast quarter-turn open and close operation\u003c\/li\u003e\n\u003cli\u003eMeets API 609 and MSS SP-67 standards; marked per MSS SP-25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wafer butterfly valve for 4-inch flanged piping systems where API 609 and MSS SP-67 compliant valves are specified.\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. Depressurize and drain the piping system fully before removing any existing valve or installing this unit. The wafer body must be centered between flanges with proper gaskets on each face before flange bolts are torqued. Confirm disc clearance in the pipe bore during assembly to avoid damage when cycling the valve.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\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: Ethylene Propylene Diene Monomer (EPDM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Lever\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Style\u003c\/strong\u003e: Wafer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: MSS SP-25 (Markings), API 609, MSS SP-67\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: NLJ120H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51544499683634,"sku":"NLJ120H","price":364.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2add512f191974b36ba03c130f2076c3_2eb50b20-e91c-4d6f-ba76-a932b9160bd8.jpg?v=1785928233","url":"https:\/\/voomisupply.com\/products\/nibco-nlj120h-4-inch-wafer-butterfly-valve-lever-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
