The Watts series LF009 features a 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. Available for sizes 1/2 to 3 inches. LF009 reduced pressure valve assembly backflow preventers block the reverse flow of liquids from backpressure or backsiphonage in a plumbing system where a potential health hazard exists. The compact modular design makes this series easy to install in tight spaces. The single cover, top-entry design allows convenient access for maintenance, and the seats are replaceable for economical repair. Available in sizes 1/4 to 3 inches.
