Description

The FEBCO 10 inch MasterSeries LF880WZ is a lead-free reduced pressure zone backflow preventer designed for high hazard/toxic applications in potable water systems. Its Z-pattern orientation and longer lay-length allow for drop-in replacement of competitor valves. Featuring an ArmorTek®-coated ductile iron body and stainless steel internal components, it offers superior corrosion resistance and durability. The integrated SentryPlus Alert® flood sensor detects excessive discharge, providing alerts when paired with an add-on connection kit. Domestic OSY shutoff valves are included. This assembly is approved by ASSE 1013, UL, FM, and AWWA C511, ensuring compliance and reliability for critical installations.

Additional Details

The FEBCO MasterSeries LF880WZ Reduced Pressure Zone Assembly is a 10 inch lead-free backflow preventer designed to protect potable drinking water systems from high hazard/toxic fluids due to backpressure and backsiphonage conditions in industrial installations and applications. This assembly features a Z-pattern orientation and a longer gate-to-gate length for drop-in replacement of competitor’s Z-pattern valves.

Features

  • Ductile iron body coated with ArmorTek®, a patented three-part advanced epoxy system, to resist microbial-induced corrosion (MIC) and protect exposed metal substrate.
  • Lead Free construction to comply with low lead installation requirements (wetted surface contains less than 0.25% lead by weight).
  • Stainless steel relief valve seat and stainless steel check components for maximum performance and durability, ensuring greater dependability and extended valve life.
  • Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • When paired with an add-on connection kit (sold separately), the flood sensor relays signals for multichannel alerts (call, email, text) to notify personnel of potential flooding.
  • Inline serviceable assembly requires no special tools for maintenance of the pressure differential relief valve and check modules.
  • Domestic OSY resilient seated gate valves and test cocks.
  • Modular and repairable pressure differential relief valve.
  • Vertical up Z-pattern installation.
  • Captured modular spring assembly; clapper check assembly.
  • Reversible and replaceable discs.
  • Field replaceable seats.

The flood sensor requires an add-on connection kit to be active. Without it, the flood sensor is a passive component that does not communicate with any other device. The information provided is not intended to replace full product installation and safety information; users must thoroughly read all installation instructions and consult governing authorities for local installation requirements.

FAQs

What is the primary purpose of the FEBCO 10 inch LF880WZ backflow preventer?

Its primary purpose is to protect potable drinking water systems from contamination by high hazard (toxic) fluids caused by backpressure and backsiphonage, commonly found in industrial installations.

Is this backflow preventer lead-free?

Yes, it features lead-free construction, meaning the wetted surfaces contacted by consumable water contain less than 0.25% lead by weight, complying with low lead installation requirements.

How does the flood sensor work, and what is required to activate it?

The flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate its alert functionality, an add-on connection kit must be purchased separately.

What type of shutoff valves are included with this assembly?

This 10 inch LF880WZ assembly comes with domestic OSY (Outside Stem & Yoke) resilient seated gate valves, which are UL Classified and FM Approved.

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

The maximum working pressure for this assembly is 175 psi (12.1 bar), and it operates continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C).
