This 1/2 inch lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering the potable water supply due to backsiphonage or backpressure. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards.

Flood Sensor & Alert Technology

• Includes a flood sensor with SentryPlus Alert® technology to detect continuous water discharges from the relief valve.
• When paired with an add-on connection kit, the sensor activates to relay alerts for potential flooding events.

Connectivity & Integration

• Connection kit options (sold separately) include BMS, cellular communication, and the Sensor Control Monitor.
• The Sensor Control Monitor enables integration with a Building Automation System (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi connectivity.
• The system automatically generates maintenance alerts for connected equipment.

Design & Construction

• Features a lead-free bronze body construction with NPT end connections.
• Equipped with a bronze strainer and quarter-turn ball valve shutoffs with tee handles.
• Includes two poppet style check valves and replaceable check seats.
• Offers a compact, space-saving design with separate access covers for the check valves and relief valve.
• The bottom-mounted relief valve has an EZ twist cover with a quarter-turn locking joint to capture the spring load during repair, facilitating disassembly.
