The valve features a cast iron body, ductile iron disc, and stainless steel stem, delivering a corrosion-resistant construction suited for demanding service environments. A Buna-N seat provides a reliable shutoff seal. The lever handle allows for quick manual actuation without tools. Rated to 200 psi maximum working pressure and 180 degrees F maximum working temperature, this valve meets the pressure and temperature demands of most HVAC hydronic, plumbing, and light industrial piping systems. Installation is performed by licensed pipefitters or plumbers.\u003c\/p\u003e\u003cp\u003eThe NLJ160H wafer butterfly valve is used in 4-inch piping runs where a compact, lightweight isolation or throttling valve is needed. The wafer design seats between two pipe flanges, making it a space-efficient alternative to full-lug or flanged body valves. Typical applications include chilled water systems, condenser water loops, HVAC hydronic circuits, and general-purpose water service piping. The lever handle suits installations where frequent manual operation or quick shutoff is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCast iron body construction for strength and durability in wet service environments\u003c\/li\u003e\n\u003cli\u003eDuctile iron disc for improved impact resistance over standard gray iron\u003c\/li\u003e\n\u003cli\u003eStainless steel stem resists corrosion and pitting under repeated cycling\u003c\/li\u003e\n\u003cli\u003eBuna-N seat provides a tight shutoff seal compatible with water and many common fluids\u003c\/li\u003e\n\u003cli\u003e200 psi maximum working pressure rating for high-demand piping systems\u003c\/li\u003e\n\u003cli\u003eLever handle enables fast manual actuation and clear open\/closed position indication\u003c\/li\u003e\n\u003cli\u003eMeets API 609, MSS SP-67, and MSS SP-25 marking standards for verified quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style wafer butterfly valve for 4-inch pipe flanged installations in commercial HVAC, plumbing, and light industrial piping systems following standard wafer face-to-face dimensions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this valve should be performed by a licensed plumber or pipefitter following applicable IPC and ASME B31.9 piping code requirements. Isolate and depressurize the system fully before removing the existing valve or installing this one. The wafer body must be centered carefully between mating flanges with appropriate gaskets to achieve a proper seal. Verify flow direction and lever clearance before final flange bolt torque to avoid binding or misalignment.\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\u003eStyle\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: Buna-N\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: 180 degrees F\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: NLJ160H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51543405953330,"sku":"NLJ160H","price":364.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b704f575f847f92becbbb50d75051b72_315c60f5-9ee9-41e2-8161-ac81e0a85b8d.jpg?v=1785918024","url":"https:\/\/voomisupply.com\/products\/nibco-nlj160h-wafer-butterfly-valve-4-inch-lever-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
