    Series LF909-FS Large reduced pressure valve assembly backflow preventer is designed to prevent the reverse flow of liquids in a plumbing system due to backpressure or backsiphonage where there is a potential health hazard. An exclusive relief valve design provides substantially improved relief valve discharge performance during emergency conditions of combined backsiphonage and backpressure. These large diameter backflow preventers are available in 2-1/2 to 10 inch sizes.

    The coating on this backflow assembly uses ArmorTek™ technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.

    This series features an integrated flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.
