Reduced Pressure Backflow Preventer Assemblies

•In a low condition, the check valves are open with the pressure between the checks, called the zone, being maintained at least 5 PSI lower than the inlet pressure, with the relief valve maintained closed. Should abnormal conditions arise under no flow or reversal of flow, the differential relief valve will open and discharge to maintain the zone at least 3 PSI lower than the supply. In resumption of normal flow, the zone 's differential pressure will resume and the relief valve will close.
