Description

This 12 inch lead free reduced pressure zone backflow preventer assembly prevents reverse flow of fire protection substances and non-potable water into potable water supplies. Its stainless steel body is lightweight, reducing shipping and installation costs, and features short end-to-end dimensions for easy retrofitting. Key features include a SentryPlus Alert flood sensor to detect relief valve discharge, capable of integrating with an optional Sensor Control Monitor connection kit for remote alerts via BAS Modbus or the Nexa Wi-Fi platform. The assembly also boasts a patented cam-check design for maximum flow at low pressure drop and a stainless steel relief valve for reduced maintenance.

SentryPlus Alert Integration

This backflow preventer includes a SentryPlus Alert flood sensor designed to detect continuous discharge from the relief valve. When paired with an add-on connection kit (such as the Watts Sensor Control Monitor Connection Kit), the sensor is activated to relay alerts for potential flooding events. The connection kit provides integration options:

  • Building Automation System (BAS) via RS-485 Modbus.
  • Nexa platform through Wi-Fi connectivity for alerts and data streaming.

The system automatically generates alerts when maintenance or service is needed for connected equipment.

Additional Details

This is a 12 inch lead free reduced pressure zone backflow preventer assembly designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and/or backpressure.

Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. 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 a flood sensor with SentryPlus Alert technology to detect continuous discharge from the relief valve.
  • Integrates with an add-on Sensor Control Monitor connection kit to deliver maintenance alerts to a Building Automation System (BAS) via RS-485 Modbus or the Nexa platform by Wi-Fi connectivity.
  • Stainless steel body is half the weight of competitive designs, reducing installation and shipping costs.
  • Short end-to-end dimensions simplify retrofit installations.
  • Cam-check assembly provides maximum flow at low pressure drop.
  • Equipped with top mounted test cocks.
  • Compact construction allows for smaller enclosures.
  • Stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs.

Construction

  • This assembly, provided without shutoff valves, consists of a short lay length lightweight stainless steel body.
  • Includes test cocks and a corrosive resistant stainless steel bottom mounted relief valve.
  • Features a patented cam-check assembly.

FAQs

What is the primary function of this backflow preventer?

This 12 inch reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and non-potable water into the potable water supply, protecting against backsiphonage and backpressure.

Does this backflow preventer include shutoff valves?

No, this assembly is supplied without shutoff valves. It consists of the main stainless steel body, test cocks, relief valve, and cam-check assembly.

How does the flood sensor feature work?

The backflow preventer incorporates a SentryPlus Alert flood sensor that detects continuous discharge from the relief valve. When paired with an optional add-on connection kit, it can relay alerts for potential flooding events to a Building Automation System or the Nexa platform via Wi-Fi.

What are the benefits of the stainless steel body?

The stainless steel body makes the assembly half the weight of competitive designs, which helps to reduce installation and shipping costs. Its short end-to-end dimensions also simplify retrofit installations.

What type of check valve assembly does this product use?
