Detector assemblies are built for fire sprinkler service: the metered bypass registers the low flows that reveal a leak or an unauthorized tap on the fire line. This model is UL Classified and C-UL Classified and FM Approved. The bypass meter reads in GPM.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes the relief valve need a drain?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. An RPZ relief valve is designed to discharge, and it can dump a large volume of water, so it must never be installed in a pit or below grade and the discharge must be piped to an adequate drain through an air gap. The air gap fitting is not included with this model and is ordered separately.\u003c\/dd\u003e\n\u003c\/dl\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Backflow Preventer - Reduced Pressure Principle Detector Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Flanged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Ductile Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure (psi):\u003c\/strong\u003e 175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Fire Protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackflow Protection:\u003c\/strong\u003e Both\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 8-375ADA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e up to 140°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASSE-1047, AWWA-C550, AWWA-C606, CSA-B64.4, C-UL, UL, FM, USC, NSF-61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly Type:\u003c\/strong\u003e RPDA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHazard Protection Level:\u003c\/strong\u003e High Health Hazard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASSE Standard:\u003c\/strong\u003e ASSE 1047\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSC FCCCHR Approved:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Protection Listing:\u003c\/strong\u003e UL Classified;C-UL Classified;FM Approved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField Testable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShutoff Valves:\u003c\/strong\u003e NRS Gate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBypass Meter:\u003c\/strong\u003e GPM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zurn","offers":[{"title":"Default Title","offer_id":55656191525163,"sku":"8-375ADA","price":27712.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/375ADA_AF_4e27261e-4361-4d76-be3d-2f117257b708.jpg?v=1790041984","url":"https:\/\/citysupplygroup.com\/products\/zurn-8-375ada","provider":"City Supply","version":"1.0","type":"link"}
