Connections

  • This assembly features flanged end connections, compliant to ASME B16.1 Class 125 and AWWA Class D Flange standards.
  • An add-on connection kit is required to activate the integrated flood sensor for communication capabilities. Available connection kit options include BMS (Building Management System), cellular communication, or the Sensor Control Monitor for integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi. Without a connection kit, the flood sensor operates as a passive component.

FAQs

What is the primary purpose of the FEBCO LF886V backflow preventer?

This backflow preventer is designed to protect potable water systems from contamination due to backpressure and backsiphonage in high hazard or toxic applications, such as industrial installations.

What is ArmorTek® coating and why is it important?

ArmorTek® is a patented three-part advanced epoxy coating applied to the ductile iron components. It's crucial for resisting microbial-induced corrosion (MIC) and protecting exposed metal surfaces, extending the life and reliability of the assembly.

How does the integrated flood sensor work?

The SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. When paired with an optional add-on connection kit (BMS, cellular, or Wi-Fi via Sensor Control Monitor), it can relay signals for multichannel alerts, notifying personnel of potential flooding.

Does this backflow preventer include shutoff valves and a bypass meter?

Yes, it includes domestic OSY (Outside Stem & Yoke) resilient wedge gate shutoff valves and a GPM (gallons per minute) metered bypass assembly. The bypass helps detect minor leaks or unauthorized water usage.

What are the main material components of the FEBCO LF886V?

The main and relief valve bodies are made of ductile iron Grade 65-45-12 with ArmorTek® coating. Key internal components like check seats, relief valve seat, disc holder, and springs are stainless steel, while the elastomer disc is silicone.
