1" LF909-FS

Series LF909-FS Small reduced pressure valve assembly backflow preventer blocks the reverse flow of polluted water entering the potable water supply, where a potential health hazard exists. An exclusive relief valve design provides substantially improved discharge performance during emergency conditions of combined backsiphonage and backpressure. Available in sizes 3/4 to 2 IN.

The series can be installed horizontally or vertically without the use of any special tools. The compact modular design facilitates maintenance for in-line repairs.

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.
