LF825YA Reduced Pressure Backflow Preventer, 1 in, FNPT, Bronze

This 1 inch lead free bronze N shaped reduced pressure zone backflow preventer assembly prevents the reverse flow of high hazard (toxic) fluids found in the water from entering into the potable water supply due to backsiphonage and or backpressure. This compact integral assembly with an extremely short lay length provides versatility and simplifies new and retrofit installations which are advantageous in areas of limited space. This assembly consists of threaded quarter turn ball valves, angle union connections, test cocks, spring loaded Y pattern check valves, and one hydraulically dependent differential relief valve. This backflow assembly contains a flood sensor with SentryPlus Alert(R) technology to detect excessive water discharges from the relief valve. When paired with an add‑on connection kit, the sensor is activated to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS‑485 Modbus or the Nexa(R) platform through Wi-Fi.
