FB0124431, Febco, 10 In Lead Free Double Check Detector Backflow Preventer Assembly, Fusion Epoxy Coated Using ArmorTek Technology, Less Gate Valves, GPM Meter

This 10 inch lead free MasterSeries(R) double check detector backflow preventer assembly prevents the backflow of pollutants due to backsiphonage and or backpressure that are objectionable but not toxic, from entering into the potable water supply. It is ideal for protection of non-health hazard cross-connections or for containment at the service line entrance. It is used primarily on fire sprinkler and standpipe systems requiring detection of unauthorized water use. This assembly without shutoff valves consists of ductile iron fused epoxy coated body construction, two in-line independent check valves, replaceable stainless steel check seats, gallons per minute metered bypass and ball valve test cocks. The maximum working pressure is 175 psi (12.06 bar). The coating on this backflow assembly uses ArmorTek(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
