909RPDA
Reduced Pressure Detector Assembly Backflow Preventers with Flood Sensor, Cast Iron, 2 1/2 - 10 IN Sizes
Series 909RPDA Reduced Pressure Detector assembly backflow preventers feature 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.
This series prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. The 909RPDA incorporates a meter to detect ground leaks and unauthorized illegal taps, greatly reducing annual water expenses. It consists of a coated cast iron body with stainless steel trim, cast iron gate valves, a pressure-differential relief valve, shutoff valves, and bronze ball-type test cocks. Maximum working pressure is 175 psi (12.06 bar).
