This 3" lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. Ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards. This assembly consists of a cast iron body, UL and FM OSY domestic resilient seated gate valves, top mounted test cocks, two in-line independent check valves, captured springs and replaceable check seats with an internal relief valve for reduced space requirements. The coating on this backflow assembly uses ArmorTek(TM) technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. This backflow assembly includes flood sensor with SentryPlus Alert(R) 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 the user of potential flooding. Add-on sensor connection kits are available for both BMS and cellular communications.
