AMF0690993, 3 IN SS Reduced Pressure Detector Backflow Preventer Assembly, OSY Shutoffs, Cam-Check Valves, Cubic Feet Meter, Backflow Flood Sensor

This 3 inch reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. This compact modular design consists of a short lay length lightweight stainless steel body, outside stem and yoke resilient seated gate valves, test cocks, thermoplastic cam-check valves, and a corrosive resistant stainless steel bottom mounted relief valve. It comes furnished with a cubic feet per minute meter to detect underground leaks and unauthorized water use. This backflow assembly contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor can send an alert to notify personnel about potential flooding. Add-on sensor connection kits are available for BMS and cellular communications.
