2 1/2 IN SS Reduced Pressure Zone Assembly Backflow Preventer, NRS Shutoff Valves, Backflow Flood Sensor

This 2 1/2 inch stainless steel reduced pressure zone assembly backflow preventer help stop the reverse flow of liquids due to backpressure or backsiphonage, where potential health hazard exists. This extremely compact and lighter than a traditional designed assembly is approved for horizontal installation in accordance with the direction of the flow arrow. This assembly consists of a stainless steel body with a quick access sleeve, torsion spring check valves, resilient seated gate valves with non-rising stem, test cocks, and a corrosive resistant stainless steel bottom mounted pressure 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.

Features

  • Features a flood sensor with SentryPlus Alert technology to detect continuous discharge from the relief valve
  • Add-on sensor connection kit to extend flood monitoring on compatible assemblies
  • Integrates with the Sensor Control Monitor to deliver maintenance alerts to BAS via RS-485 Modbus or the Nexa platform by Wi-Fi connectivity
  • 304 (Schedule 40) stainless steel housing and sleeve
  • UL and FM outside stem and yoke resilient seated gate valves
  • Replaceable check disc rubber
  • Bottom mounted cast stainless steel relief valve
  • Compact design allows small enclosures to be used
  • Groove couplings for ease of installation and pipe alignment
