Additional Details

This 2 inch lead free N shaped reduced pressure zone backflow preventer assembly prevents the reverse flow of high hazard (toxic) fluids from entering the potable water supply due to backsiphonage and/or backpressure. Its compact integral design provides versatility for new and retrofit installations, especially in areas with limited space. The assembly includes a lead free body, threaded quarter turn ball valves, test cocks, spring loaded Y pattern check valves, and one hydraulically dependent differential relief valve.

The LF825YA series features a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. When paired with an add-on connection kit, the sensor activates to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor, which enables integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Features

  • Prevents reverse flow of high hazard (toxic) fluids into potable water supply
  • Lead free construction to comply with installation requirements
  • Integrated flood sensor with SentryPlus Alert® technology for discharge detection
  • Flood alerts activated with add-on sensor connection kit, compatible with BMS and cellular communication
  • Sensor Control Monitor integrates smart devices with BAS via RS-485 Modbus or Nexa® platform through Wi-Fi
  • Modular relief valve and check valves for easy maintenance
  • Compact, integral N shaped assembly simplifies new and retrofit installations
  • Integral flanged union connections allow assembly removal for freeze protection or maintenance without spool substitution
  • Replaceable seat rings for longer valve life
  • Low head loss for optimum performance

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

FAQs

What types of fluids does this backflow preventer protect against?

This reduced pressure zone assembly protects potable water supplies from the reverse flow of high hazard (toxic) fluids found in industrial plants, hospitals, morgues, mortuaries, and chemical plants, as well as irrigation systems and boiler feeds.

What is SentryPlus Alert® technology?

SentryPlus Alert® technology refers to the flood sensor integrated into the relief valve of the assembly. It detects excessive water discharges and, when activated with an add-on connection kit, relays alerts to service personnel to prevent flooding and costly damage.

What connections does this backflow preventer use?

This assembly features NPT ANSI/ASME B1.20.1 threaded end connections. It also includes integral flanged unions between the mainline valve body and the ball valve shutoffs to allow for field removal.

What are the benefits of the modular design?

The modular relief valve and check valve internal components are designed for ease of maintenance. This allows for servicing without removing the entire valve body from the line, reducing installation time, labor costs, and materials.

What certifications does this backflow preventer hold?

The FEBCO LF825YA-QT-RP-FS assembly is approved by the Foundation for Cross-Connection Control and Hydraulic Research at USC, complies with AWWA C511, and is certified to ASSE 1013, CSA B64.4, and NSF/ANSI 61-G standards.
