Additional Details

This 6 inch FEBCO MasterSeries LF876W/WZ Double Check Detector Backflow Preventer Assembly, Type II, is designed for the Z-pattern flow orientation, specifically for drop-in replacement of competitor's Z-pattern valves.

It is engineered to prevent the reverse flow of polluted water from entering the potable water supply due to backsiphonage or backpressure, primarily for use in fire protection systems to detect system leakage or unauthorized water usage.

Construction & Features

  • Features a durable ductile iron body construction (Grade 65-45-12)
  • Utilizes ArmorTek®, a patented three-part advanced epoxy system, to resist microbial-induced corrosion (MIC) and protect exposed metal surfaces
  • Designed as a competitor drop-in replacement lay length for Z-pattern valves
  • Equipped with two in-line independent check valves, stainless steel check seats, and silicone elastomer discs
  • Includes a gallons per minute (GPM) metered bypass to detect potential underground water leaks and unauthorized water usage
  • Features in-line serviceable assembly requiring no special tools for main valve maintenance
  • Comes with field replaceable seats and discs and a captured modular spring assembly
  • Built with lead-free wetted surfaces, containing less than 0.25% lead by weight

FAQs

What is the primary function of this backflow preventer assembly?

This assembly's primary function is to prevent the reverse flow of polluted water into the potable water supply due to backsiphonage or backpressure, especially in non-health hazard (pollutant) applications like fire sprinkler systems.

What does the 'Z-Pattern Lay Length' refer to?

The 'Z-Pattern Lay Length' indicates that this assembly is configured for a Z-shaped flow orientation, and its dimensions are specifically designed to allow for a drop-in replacement of existing competitor's Z-pattern backflow preventer valves.

Does this model come with shutoff valves?

No, this specific model (6 LF876-WZ-LG-GPM) is configured as 'Less Shutoff Valves', meaning the inlet and outlet shutoff valves are not included with the assembly.

What is ArmorTek coating and its benefit?

ArmorTek is a patented three-part advanced epoxy system applied to the iron components. It is engineered to reduce microbial-induced corrosion (MIC) and protect the exposed metal substrate, enhancing the durability and lifespan of the backflow preventer.

What is the purpose of the GPM meter in the bypass line?

The Gallons Per Minute (GPM) meter in the auxiliary bypass line is designed to detect potential underground water leaks within the system and identify any unauthorized water usage, providing valuable monitoring capabilities.
