This LF886WZ assembly is designed for Z-pattern orientation and provides a longer lay-length for direct drop-in replacement of competitor's Z-pattern valves. It is intended for installation on potable water supply lines at points of cross-connection to protect against high hazard/toxic backpressure and backsiphonage conditions. The main valve's end connections are compliant to ASME B16.1 Class 125 and AWWA Class D Flange standards. The integral flood sensor requires an add-on connection kit (available separately) for active communication via BMS, cellular, or the Nexa® platform for flood alerts.

Additional Details

The 10 inch FEBCO MasterSeries LF886WZ Lead Free Reduced Pressure Zone Detector Assembly is designed to protect potable drinking water systems from backpressure and backsiphonage conditions in high hazard/toxic applications.

This assembly features a longer lay-length for drop-in replacement of competitor’s Z-pattern valves and includes a flood sensor to detect excessive water discharges.

Main Valve Features

  • Stainless steel relief valve seat and stainless steel check components for maximum performance and durability
  • Longer gate-to-gate length for drop-in replacement of longer valves
  • Inline serviceable assembly; no special tools required
  • Captured modular spring assembly
  • Reversible and replaceable discs
  • Field replaceable seats
  • Ductile iron valve body design
  • ArmorTek coating technology to resist corrosion of internals
  • Modular and repairable pressure differential relief valve
  • Clapper check assembly
  • Captured O-ring design
  • Sensor on relief valve for flood detection, activated by add-on connection kit for BMS or cellular network communication

Auxiliary Bypass Features

  • Compact design; remains in main valve assembly profile
  • Inline serviceable 3/4 inch check assembly; no special tools required
  • No special tools required for servicing
  • Field replaceable seat and disc
  • Detect potential underground water leaks
  • Detect unauthorized water usage
  • Totalizing cubic feet per minute (CFM) water meter

An add-on connection kit is required to activate the flood sensor. Without the connection kit, the flood sensor is a passive component that does not communicate with any other device. Watts® is not responsible for the failure of alerts due to connectivity issues, power outages, or improper installation. Always read installation instructions and inquire with governing authorities for local requirements.

FAQs

What is the primary use of the FEBCO LF886WZ backflow preventer?

This backflow preventer is designed to protect potable drinking water systems from backpressure and backsiphonage conditions, especially in high hazard/toxic applications where local codes mandate such protection.

Does this assembly include shutoff valves?

No, this specific model (LF886WZ-LG-CFM-FS) comes "Less Shutoff Valves" (LG). Shutoff valves would need to be sourced separately if required for your installation.

How does the flood sensor work and what does it detect?

The integral flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. It requires a separate add-on connection kit to activate communication and relay alerts via BMS, cellular, or Wi-Fi to notify personnel of potential flooding.

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

The maximum working pressure for this unit is 175 psi (12.1 bar). It can operate continuously in a temperature range of 33°F to 140°F (0.5°C to 60°C).

What is ArmorTek® coating and why is it important?

ArmorTek® is a patented three-part advanced epoxy system applied to the iron components of the backflow preventer. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces, extending the life and reliability of the assembly.
