Description

The FEBCO MasterSeries LF886V is a 6-inch lead-free reduced pressure zone detector backflow preventer assembly, designed to protect potable water systems from high hazard toxic fluids due to backpressure or backsiphonage. Its ductile iron body features ArmorTek® advanced epoxy coating for superior corrosion resistance, including protection against microbial-induced corrosion. This assembly includes domestic OSY shutoff valves, stainless steel internal components, and a Cubic Feet Per Minute (CFM) metered bypass for leak detection. A key feature is the SentryPlus Alert® flood sensor, which notifies personnel of relief valve discharges, requiring an add-on kit for activation. It is UL Classified, FM Approved, and ASSE 1047 compliant. Item number F683217.

How the Flood Sensor Connects

  • The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve.
  • To activate its alert functionality, an add-on connection kit is required. Without this kit, the sensor acts as a passive component.
  • Connection kit options include direct BMS integration, cellular communication, or the Sensor Control Monitor for integration with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform through Wi-Fi.

Main Connections

  • This 6-inch assembly features end connections compliant with ASME B16.1 Class 125 and AWWA Class D Flange standards.

Additional Details

This 6 inch lead free MasterSeries® LF886V Reduced Pressure Zone Detector backflow preventer assembly is designed to protect potable water systems from high hazard (toxic) fluids caused by backpressure and backsiphonage, commonly found in industrial installations and applications.

Advanced Corrosion Protection

  • Features ArmorTek®, a patented three-part advanced epoxy coating system applied to internal and external surfaces.
  • Engineered to reduce both microbial-induced corrosion (MIC) and protect exposed metal substrate for extended durability.

Flood Detection with SentryPlus Alert® Technology

  • Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • Relays a signal that triggers a multichannel alert (call, email, text) to notify personnel about potential flooding.
  • 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.

Main Valve Features

  • Ductile iron body construction.
  • Stainless steel relief valve seat and stainless steel check components for maximum performance and durability.
  • Inline serviceable assembly; no special tools required for maintenance.
  • Captured modular spring assembly.
  • Reversible and replaceable discs.
  • Field replaceable seats.
  • Modular and repairable pressure differential relief valve.
  • Clapper check assembly.
  • Captured O-ring design.

Auxiliary Bypass Features

  • Compact design; remains in main valve assembly profile.
  • Equipped with a Cubic Feet Per Minute (CFM) water meter to totalize flow.
  • Inline serviceable 3/4 inch check assembly; no special tools required.
  • Field replaceable seat and disc.
  • Designed to detect potential underground water leaks and unauthorized water usage.

Lead Free Compliance

  • The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight, complying with low lead installation requirements.

FAQs

What type of applications is the FEBCO LF886V backflow preventer suitable for?

This backflow preventer is designed for high hazard/toxic applications in potable drinking water systems, primarily used in industrial installations and applications where local codes mandate protection against contaminated water.

What does "Lead Free" mean for this product?

"Lead Free" means that the wetted surface of this product, which comes into contact with consumable water, contains less than 0.25% of lead by weight, complying with low lead installation requirements.

How does the ArmorTek® coating benefit this backflow preventer?

The ArmorTek® coating is a patented three-part advanced epoxy system applied to internal and external surfaces. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates, enhancing the durability and lifespan of the assembly.

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

The integrated flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. To activate its alert functionality and relay signals for multichannel notifications (call, email, text), an add-on connection kit (BMS, cellular, or Sensor Control Monitor) is required.

What is the maximum operating pressure and temperature range for this 6-inch LF886V assembly?

This 6-inch LF886V backflow preventer has a maximum working pressure of 175 psi (12.1 bar) and operates continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C).
