Additional Details

The Colt 6 inch reduced pressure zone backflow preventer assembly is designed to protect potable water systems from contamination due to backsiphonage or backpressure, ideal for health hazard applications in fire protection and industrial settings.

This assembly incorporates a SentryPlus Alert® flood sensor to detect and signal excessive water discharge from the relief valve, helping to prevent potential flooding when paired with an add-on connection kit.

Construction & Features

  • Extremely compact design, up to 70% lighter than traditional backflow preventers
  • Constructed with a Type 304 (Schedule 40) stainless steel housing and sleeve
  • Includes two independent Link Check modules and a differential pressure relief valve
  • Equipped with domestic outside stem and yoke (OSY) resilient seated gate valves and required test cocks
  • Groove couplings for easy installation and integral pipeline adjustment
  • Patented link check design ensures lowest pressure loss and ease of serviceability
  • Reversible elastomer check discs for longevity
  • Approved for horizontal installation

Flood Detection System

  • Integrated SentryPlus Alert® flood sensor detects continuous discharge from the relief valve
  • Activation requires an add-on sensor connection kit (sold separately)
  • Connection kit options support integration with building management systems (BMS), cellular communication, or the Sensor Control Monitor for BAS via RS-485 Modbus or Nexa® platform via Wi-Fi

NOTICE: An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component and will not communicate with any other device.

FAQs

What is the primary purpose of this backflow preventer?

This Colt 6 inch reduced pressure zone backflow preventer assembly is designed to protect potable water systems from contamination by preventing reverse flow (backsiphonage and backpressure) of non-potable substances, especially in fire protection and health hazard applications.

What material is the housing and sleeve made from?

The housing and sleeve of this backflow preventer are constructed from durable Type 304 (Schedule 40) stainless steel, ensuring longevity and resistance to corrosion.

How does the SentryPlus Alert® flood sensor work?

The integrated SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate the sensor and receive alerts for potential flooding, an add-on sensor connection kit (sold separately) is required.

What is the maximum operating pressure and temperature range for this unit?

This backflow preventer has a maximum working pressure of 175 PSI (12.1 bar) and operates effectively within a temperature range of 33°F to 140°F (0.5°C to 60°C).

What type of shutoff valves are included with this assembly?

This assembly includes domestic outside stem and yoke (OSY) resilient seated gate valves, which are UL Classified and FM Approved, and feature an integrated supervisory switch option.
