Connection and Monitoring
This FEBCO LF886V assembly requires an add-on connection kit to activate the flood sensor and enable communication.
Connection kit options include BMS (Building Management System) integration via RS-485 Modbus or connectivity to the Nexa® platform through Wi-Fi.
The assembly is equipped with domestic OSY shutoff valves for easy isolation.
The FEBCO 4 inch Lead Free MasterSeries LF886V Reduced Pressure Zone Detector Assembly with domestic OSY shutoffs protects potable drinking water systems from high hazard/toxic backpressure and backsiphonage conditions.
This detector assembly is designed for industrial installations and applications where local codes mandate protection against non-potable quality water entering the system.
Protection & Durability
Features ArmorTek® coating, a patented three-part advanced epoxy system engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates.
Includes a stainless steel relief valve seat and stainless steel check components for maximum performance and durability.
Ductile iron valve body design ensures ruggedness and extended service life.
Flood Detection & Monitoring
Equipped with a SentryPlus Alert® flood sensor on the relief valve to detect excessive water discharges.
When paired with an add-on connection kit, the sensor relays a signal for multichannel alerts (call, email, text) to notify personnel about potential flooding events.
An add-on connection kit is required to activate the flood sensor for communication; without it, the sensor is a passive component.
Bypass Assembly
A compact auxiliary bypass line detects potential underground water leaks and unauthorized water usage.
The bypass includes an inline serviceable 3/4 inch check assembly with a field replaceable seat and disc.
Serviceability
Designed for inline servicing with no special tools required.
Features a captured modular spring assembly, reversible and replaceable discs, and field replaceable seats.

FAQs
What is the primary purpose of the FEBCO 4 inch LF886V assembly?
Its primary purpose is to protect potable drinking water systems from contamination due to high hazard (toxic) fluids caused by backpressure or backsiphonage, in accordance with local governing water utility codes.
What is ArmorTek® coating and what are its benefits?
ArmorTek® is a patented three-part advanced epoxy coating system applied to the ductile iron body. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates, enhancing the assembly's durability and lifespan.
How does the flood sensor function, and what is needed to activate it?
The SentryPlus Alert® flood sensor detects excessive water discharges from the relief valve. To activate its communication features and receive alerts (call, email, text), an add-on connection kit is required. Without the kit, the sensor remains a passive component.
What are the key materials used in the construction of this backflow preventer?
The main valve and relief valve bodies are constructed from ductile iron Grade 65-45-12. The relief valve seat, check components, and springs are made of stainless steel, while the elastomer discs are silicone.
What is the maximum operating pressure and temperature range for this assembly?
The maximum working pressure for this assembly is 175 psi (12.1 bar). It operates effectively within a temperature range of 33°F to 140°F (0.5°C to 60°C).
