909RPDA
Reduced Pressure Detector Assembly Backflow Preventers, Cast Iron
Series 909RPDA reduced pressure detector assembly backflow preventers are designed to prevent the reverse flow of fire protection system substances from being pumped or siphoned into 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. Series 909RPDA provides maximum flow at low pressure drop utilizing the air-in/water-out design principle for protection during emergency combined backsiphonage and backpressure conditions. Maximum working pressure is 175 psi (12.06 bar).
The coating on this backflow assembly uses ArmorTek™ technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
