Additional Details

This 10 inch Lead Free MasterSeries Reduced Pressure Detector Backflow Preventer Assembly protects potable water supplies from high hazard (toxic) fluids by preventing both backpressure and backsiphonage.

Primary Use

  • Designed for installation on potable water supplies at cross-connection points
  • Protects against backpressure and backsiphonage conditions in high hazard/toxic applications

Construction & Durability

  • Features a robust ductile iron main valve body and relief valve body
  • Equipped with a patented ArmorTek® powder coating, applied to internal and external surfaces, for advanced protection against electrochemical corrosion and microbial-induced corrosion (MIC)
  • Utilizes stainless steel check seats, relief valve seat, disc holder, and springs for maximum performance and durability
  • Elastomer discs are made from silicone

Bypass & Detection

  • Includes a detector bypass assembly with a 5/8 inch x 3/4 inch totalizing cubic feet per minute (CFM) water meter
  • Integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve
  • An add-on connection kit (sold separately) can integrate the flood sensor for remote alerts via BMS, cellular communication, or the Nexa® platform via Wi-Fi

Important Note: This specific configuration, supplied with the "Less Shutoff Valves" (LG) option, is not a UL Classified or FM Approved assembly. These approvals require an assembly configured with UL Classified and FM Approved OS&Y resilient wedge gate valves.

FAQs

What is the primary function of this backflow preventer assembly?

This 10 inch Lead Free Reduced Pressure Detector Backflow Preventer Assembly protects potable water supplies from contamination by preventing both backpressure and backsiphonage conditions in high hazard (toxic) applications.

Is this specific backflow preventer assembly UL Classified or FM Approved?

No, this specific configuration, which is supplied without shutoff valves (LG option), is explicitly noted as not being a UL Classified or FM Approved assembly. These approvals require the inclusion of UL Classified and FM Approved OS&Y resilient wedge gate valves.

What kind of corrosion protection does this assembly feature?

The assembly features a patented ArmorTek® powder coating applied to both internal and external surfaces. This advanced epoxy coating system is designed to provide integrated protection against electrochemical corrosion and microbial-induced corrosion (MIC).

Does this assembly include shutoff valves?

No, this specific LF866-LG-CFM-FS assembly is supplied with the "Less Shutoff Valves" (LG) option, meaning shutoff valves are not included and must be sourced and installed separately.

What is the purpose of the flood sensor?

The integrated flood sensor with SentryPlus Alert® technology is designed to detect excessive water discharges from the relief valve. It can be connected via an add-on kit to provide remote alerts for potential flooding events.
