This 3 inch lead free reduced pressure zone backflow preventer assembly protects potable water supplies from contamination caused by backsiphonage and backpressure.

It is designed for use in continuous pressure piping applications and at cross-connections identified as health hazards, helping to prevent the reverse flow of fire protection substances and non-potable water into the drinking water supply.

Key Features

• Features SentryPlus Alert® technology with a flood sensor to detect continuous discharge from the relief valve.
• An add-on sensor connection kit (sold separately) is required to activate the flood sensor and extend flood monitoring capabilities.
• Connection kit options allow integration with Building Automation Systems (BAS) via RS-485 Modbus, the Nexa® platform through Wi-Fi, or via BMS and cellular network communication.
• Constructed with a stainless steel body, making it approximately half the weight of competitive designs, which reduces installation and shipping costs.
• Short end-to-end dimensions facilitate easy retrofitting in existing installations.
• Patented cam-check assembly provides maximum flow with low pressure drop.
• Compact modular design allows for smaller enclosures and features a single access cover for in-line repairs without special tools.
• Stainless steel relief valve with a balanced rolling diaphragm eliminates sliding seals and lowers maintenance requirements.
