It uses two independent check modules with a differential pressure relief valve located between and below them, together with shutoff valves and test cocks.\u003c\/p\u003e\n\u003cp\u003eA metered bypass provides a means of monitoring unauthorized water use from the fire protection system. This metering function is not an electronic early-warning alarm for backflow events. The housing and access sleeve are 304 Schedule 40 stainless steel. The listed options are 3-inch OS\u0026amp;Y, 4-inch grooved butterfly N-pattern, and 8-inch OS\u0026amp;Y.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eAmes Fire \u0026amp; Waterworks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeries \/ Configuration\u003c\/th\u003e\n\u003ctd\u003eC500 \/ C500N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStore SKUs\u003c\/th\u003e\n\u003ctd\u003eC500OSY-0300, C500NBFG-0400, C500OSY-0800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNominal Sizes\u003c\/th\u003e\n\u003ctd\u003e3, 4, and 8 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShutoff Configuration\u003c\/th\u003e\n\u003ctd\u003e3-inch OS\u0026amp;Y; 4-inch grooved butterfly, N-pattern; 8-inch OS\u0026amp;Y\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHousing and Sleeve\u003c\/th\u003e\n\u003ctd\u003e304 Schedule 40 stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Working Pressure\u003c\/th\u003e\n\u003ctd\u003e175 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater Temperature Range\u003c\/th\u003e\n\u003ctd\u003e33°F to 140°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCheck Discs\u003c\/th\u003e\n\u003ctd\u003eReversible silicone or EPDM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSprings, Pins, and Fasteners\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eShutoff valves provide isolation; they are not described as allowing service of the assembly while keeping flow through it uninterrupted.
