The 10 inch Lead Free Reduced Pressure Detector Backflow Preventer Assembly provides crucial protection for potable water systems against contamination from backpressure and backsiphonage, particularly where health hazards may exist. Its extremely compact design is up to 70% lighter than traditional models and is approved for horizontal installation.
This assembly integrates a SentryPlus Alert® flood sensor to detect excessive water discharges from the relief valve, helping to prevent costly flooding. When paired with an optional add-on connection kit, the sensor activates to relay alerts to facility personnel through various communication methods, including BMS, cellular networks, or integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
Construction & Components
- Housing and sleeve constructed from 304 (Schedule 40) stainless steel for durability and corrosion resistance.
- Features two independent torsion spring check modules with patented torsion spring design for lowest pressure loss.
- Equipped with UL Classified and FM Approved outside stem and yoke (OSY) resilient seated gate valves.
- Includes a corrosive resistant bottom mounted pressure relief valve.
- A metered bypass is furnished to detect underground leaks, unauthorized water use, or theft of water from fire sprinkler systems.
- Designed for unmatched ease of serviceability with replaceable check disc rubber.
-
Groove fittings allow for integral pipeline adjustment.
An add-on connection kit is required to activate the flood sensor's communication features; without it, the sensor operates passively.
