Installed inline to protect potable water supplies from contamination, this assembly relies on a differential pressure relief valve located between two independently operated check valves to isolate backpressure and backsiphonage effectively. To maintain compliance with NFPA 13, NFPA 14, and NFPA 25 inspection, testing, and maintenance mandates, this complete unit incorporates integrated supervisory switches for reliable valve position monitoring during emergency water supply activation.\u003c\/p\u003e \u003cp\u003eThis assembly provides a fully integrated solution featuring grooved-end butterfly shutoff valves in a BFG configuration, allowing fast mechanical connections directly into grooved piping layouts. Built with a corrosion-resistant stainless-steel body, it provides long-term durability in demanding plumbing and fire safety environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cb\u003eStainless Steel Body:\u003c\/b\u003e Resists corrosion to extend service life in harsh plumbing and fire protection environments.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eGrooved-End Butterfly Valves:\u003c\/b\u003e Speeds up mechanical installations with standard grooved connections.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eIntegrated Supervisory Switches:\u003c\/b\u003e Monitors valve status remotely to support life safety compliance.\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Ships as an entire backflow unit rather than a standalone valve component.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ctable\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003e\u003cb\u003eParameter\u003c\/b\u003e\u003c\/th\u003e \u003cth\u003e\u003cb\u003eSpecification\u003c\/b\u003e\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eManufacturer \/ Brand\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eZurn Wilkins\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eModel \/ Series Number \/ SIN\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003e375AST (SKU: 375ASTBG-0300)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eConnection \/ Thread Size \u0026amp; Type\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003e3-inch Grooved-End\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003ePressure Rating (WWP \/ Max Working Pressure)\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eN\/A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eK-Factor\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eN\/A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eTemperature Rating \/ Response Type\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eN\/A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eMaterial \/ Body Construction\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eStainless Steel\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eAgency Listings \u0026amp; Approvals\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eN\/A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cb\u003eApplicable NFPA Standards\u003c\/b\u003e\u003c\/td\u003e \u003ctd\u003eNFPA 13, NFPA 14, NFPA 25\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e\n\u003c\/table\u003e \u003cp\u003eConfirm local AHJ (Authority Having Jurisdiction) installation requirements, flow rates, and current manufacturer specifications before ordering. \u003ca href=\"#\"\u003eView SupplyNet model and configuration details\u003c\/a\u003e\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":46202649936120,"sku":"375ASTBG-0300","price":4369.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/7183\/3336\/files\/image_20261017_214345.jpg?v=1792252074","url":"https:\/\/fireprotectionparts.net\/products\/zurn-wilkins-375ast-3-inch-reduced-pressure-backflow-assembly","provider":"Fire Protection Parts","version":"1.0","type":"link"}
