LF009 Reduced Pressure Backflow Preventer, 2-1/2 in, Flange, Cast Iron

This 2 1/2 inch 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. This assembly consists of a cast iron body, non-rising stem 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 contains an integrated 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.
