AMF0691821, 4 IN SS Reduced Pressure Zone Backflow Preventer Assembly, Less Shutoff, Cam-Check Valves, Red Silicone Internals, Backflow Flood Sensor

This 4 inch lead free 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. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. 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 assembly without the shutoff valves consists of a short lay length lightweight stainless steel body, test cocks, corrosive resistant stainless steel bottom mounted relief valve, and a patented cam-check assembly with red silicon rubber internals. 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.
