• Flood sensor with SentryPlus Alert technology to detect water discharges from the relief valve Flood alerts feature available with add-on sensor connection kit Stainless steel body is half the weight of competitive designs reducing installation and shipping costs Short end-to-end dimensions makes retrofit easy Cam-check assembly provides maximum flow at low pressure drop Top mounted test cocks Compact construction for smaller enclosures Stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs Stainless steel construction provides long term corrosion resistance and maximum strength

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 back siphonage 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 consists of a short lay length lightweight stainless steel body, resilient seated outside stem and yoke shutoff valves, test cocks, corrosive resistant stainless steel bottom mounted relief valve, and a patented cam-check assembly. 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.
