This precision-engineered backflow preventer installs directly into industrial, commercial, and fire sprinkler networks to block backflow effectively while minimizing pressure loss during high-demand events. It satisfies stringent life safety mandates by complying with NFPA 13 and NFPA 14 standards for fire sprinkler and standpipe systems, fulfilling critical code requirements for containment.\u003c\/p\u003e \u003cp\u003eThe integrated dual check mechanism blocks reverse flow while preserving system flow rates. The ductile iron body provides high mechanical strength and excellent corrosion resistance for demanding industrial environments. Reliable seals and seats are engineered for longevity and frequent cycling under the variable pressure loads typical of fire protection networks. Flexible integration offers compatibility with NRS or grooved connections to simplify installation in both new construction and retrofit projects.\u003c\/p\u003e \u003ctable\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e \u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eManufacturer \/ Brand\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eZurn Wilkins\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eModel \/ Series Number \/ SIN\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e950XLT \/ 950XLT-0150\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eConnection \/ Thread Size \u0026amp; Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003e1½-inch; confirm end-connection details against exact-model manufacturer documentation\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003ePressure Rating (WWP)\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eStandard Commercial\/Industrial Maximum Working Pressure\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eK-Factor\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eN\/A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eTemperature Rating \/ Response Type\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eNon-potable water operating temperature limits\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eMaterial \/ Body Construction\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eDuctile Iron\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eAgency Listings \u0026amp; Approvals\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eUL Listed (UL 312), FM Approved\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eApplicable NFPA Standards\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eNFPA 13, NFPA 14\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\n\u003c\/table\u003e \u003cp\u003eVerify all local Authority Having Jurisdiction (AHJ) mandates and cross-connection control bylaws prior to installation, and ensure the selected valve orientation and working pressure align with system engineering drawings.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDocumentation:\u003c\/strong\u003e \u003ca href=\"#\"\u003eDownload Manufacturer Technical Data \u0026amp; Cut Sheet (PDF)\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Zurn Wilkins","offers":[{"title":"Default Title","offer_id":46202654294264,"sku":"950XLT-0150","price":922.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/7183\/3336\/files\/image_20261017_213148_01e183a2-efae-4717-9740-4802512be273.jpg?v=1792251370","url":"https:\/\/fireprotectionparts.net\/products\/zurn-wilkins-950xlt-1-1-2-inch-double-check-valve-assembly","provider":"Fire Protection Parts","version":"1.0","type":"link"}
