This 2 1/2 inch lead free reduced pressure zone backflow preventer assembly is engineered to protect the potable water supply from contamination due to backsiphonage and backpressure of hazardous materials. It is suitable for continuous pressure piping applications and cross-connections identified as health hazards, including those involving fire protection substances.

Key Features

• Equipped with a flood sensor featuring SentryPlus Alert® technology to detect excessive water discharge from the relief valve.
• Requires an add-on connection kit (available separately) to activate the flood sensor for BMS, cellular communication, or integration with BAS via RS-485 Modbus or Nexa® platform via Wi-Fi.
• Constructed with a lightweight stainless steel body, offering long-term corrosion resistance and maximum strength.
• Designed with short end-to-end dimensions for easy retrofitting.
• Features a patented cam-check assembly that provides maximum flow at low pressure drop.
• Compact modular design allows for smaller enclosures and facilitates easy in-line maintenance with a single access cover.
• A stainless steel relief valve with a balanced rolling diaphragm eliminates sliding seals and reduces maintenance costs.
• Internal parts include red silicone rubber internals.
• Includes test cocks for easy testing and maintenance.
• This model is supplied less shutoff valves (gates).

NOTICE: An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component that has no communication with any other device.
