Description

The Colt 6 inch C400N-OSY-FS Reduced Pressure Zone Backflow Preventer Assembly is designed to protect potable water systems from contamination. This lead-free unit features a durable Type 304 stainless steel housing, resilient seated OS&Y gate valves with an integrated supervisory switch, and grooved end connections for ease of installation. It includes a SentryPlus Alert® flood sensor to detect excessive relief valve discharge, which relays alerts when paired with an add-on connection kit (sold separately). Rated for 175 PSI and temperatures from 33°F to 140°F, it is approved for horizontal N-pattern health hazard installations.

Installation & Connections

  • This assembly is approved for horizontal N pattern installation, provided it is installed strictly in accordance with the direction of the flow arrow.
  • The unit features groove couplings on both the inlet and outlet, designed for easy installation and integral pipeline adjustment with compatible grooved piping systems.

Flood Sensor Activation

An add-on sensor connection kit (sold separately) is required to activate the flood sensor's alert capabilities. Without this kit, the flood sensor operates as a passive component and will not communicate with other devices. Connection kit options include BMS, cellular communication, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Additional Details

This Colt 6 inch lead free reduced pressure zone backflow preventer assembly is engineered to protect potable water systems from contamination caused by backsiphonage and backpressure. It is ideal for continuous pressure piping applications and at cross-connections identified as health hazards.

Construction & Features

  • Features an extremely compact design that is 70% lighter than traditional models, allowing for smaller enclosures.
  • Constructed with a durable Type 304 (Schedule 40) stainless steel housing and sleeve for long-lasting performance.
  • Equipped with resilient seated gate valves with outside stem and yoke (OS&Y), which include an integrated supervisory switch.
  • Utilizes groove couplings for easy installation and integral pipeline adjustment.
  • Incorporates torsion spring check modules and a patented link check design for lowest pressure loss and unmatched ease of serviceability.
  • Includes replaceable check disc rubber and drip tight shutoff valves.
  • A flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve.
  • The flood alert feature is activated with an add-on sensor connection kit (sold separately) to relay alerts for potential flooding events.

Materials

  • Housing & Sleeve: Type 304 (Schedule 40) stainless steel
  • Elastomers: EPDM, silicone, and Buna 'N'
  • Link Checks: Noryl®, stainless steel
  • Check Discs: Reversible silicone or EPDM
  • Test Cocks: Lead Free* bronze body
