Compatibility & Connections

This FEBCO MasterSeries LF886WZ Reduced Pressure Zone Detector Assembly is designed with a longer lay-length to provide direct drop-in replacement for competitor’s Z-pattern backflow preventer valves of the same size. The assembly's end connections are compliant to ASME B16.1 Class 125 and AWWA Class D Flange standards. For the flood sensor to relay alerts, an add-on connection kit is required. These kits support integration with Building Management Systems (BMS), cellular networks, or the Sensor Control Monitor for Modbus/Nexa® Wi-Fi connectivity.

Additional Details

This 10 inch lead free MasterSeries® Reduced Pressure Zone Detector Assembly (Type II) is designed to protect potable water systems from high hazard (toxic) fluids due to backpressure and backsiphonage in industrial and commercial installations.

It features a longer lay-length for drop-in replacement of competitor's Z-pattern valves and includes a flood sensor with SentryPlus Alert® technology for continuous discharge detection.

Key Features

  • Provides protection against backpressure and backsiphonage for high hazard/toxic applications.
  • ArmorTek® advanced epoxy coating applied to ductile iron components for enhanced corrosion resistance.
  • Designed for drop-in replacement of competitor's Z-pattern valves, featuring a longer gate-to-gate length.
  • Includes domestic outside stem and yoke (OS&Y) shutoff valves, UL Classified and FM Approved.
  • Equipped with a gallons per minute (GPM) metered bypass to detect potential leaks and unauthorized water usage.
  • Features a flood sensor with SentryPlus Alert® technology on the relief valve to detect excessive water discharges.
  • The flood sensor can be activated with an add-on connection kit for relaying alerts via BMS, cellular communication, or the Sensor Control Monitor (Modbus/Nexa® Wi-Fi).
  • Constructed with stainless steel relief valve seat and stainless steel check components for maximum performance and durability.
  • Inline serviceable check and relief valve assemblies, requiring no special tools.

An add-on connection kit is required to activate the flood sensor's alert relay functionality. Without this kit, the sensor operates as a passive component only.

FAQs

What is the primary function of the 10 inch MasterSeries LF886WZ RPDA?

Its primary function is to protect potable drinking water systems from contamination due to backpressure and backsiphonage of high hazard (toxic) fluids, commonly found in industrial and commercial applications.

How does the flood sensor feature work on this assembly?

The integrated SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate its alert relay functionality, an add-on connection kit is required, which can provide alerts via BMS, cellular, or Wi-Fi.

What type of shutoff valves are included with this assembly?

This assembly comes with domestic outside stem and yoke (OS&Y) resilient seated shutoff valves, which are UL Classified and FM Approved.

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

The operating temperature range for this assembly is 33°F to 140°F (0.5°C to 60°C), making it suitable for continuous use within these temperatures.

Is the 10 inch LF886WZ RPDA suitable as a replacement for existing backflow preventers?

Yes, it is designed with a longer gate-to-gate lay-length, specifically for drop-in replacement of competitor's Z-pattern reduced pressure detector assemblies.
