This 2 1/2 inch lead free reduced pressure zone backflow preventer assembly is designed to provide cross-connection control protection of the potable water supply. It prevents the reverse flow of polluted water from entering the potable water supply due to backsiphonage and/or backpressure.

It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance.

Key Features

• Features an epoxy coated cast iron body with ArmorTek®, a patented 3-part advanced epoxy coating system engineered to limit both microbial induced corrosion (MIC) and exposed metal substrate corrosion.
• Equipped with non-rising stem resilient seated gate valves, captured spring check valves, replaceable seats, and top mounted test cocks.
• Includes a field reversible pressure differential relief valve with a unique patented air-in and water-out design for high capacity discharge performance during emergency conditions.
• Constructed with Lead Free* materials to comply with installation requirements.

Flood Sensor Technology

• Contains a flood sensor with SentryPlus Alert® 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 to facility personnel for corrective action.
• The sensor supports connectivity options including BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
