FAQs

What is the primary function of the FEBCO 3 LF880V-LG-FS assembly?

This 3-inch lead-free reduced pressure zone backflow preventer assembly is designed to protect water systems against high hazard (toxic) fluids, particularly in industrial installations and applications.

Does this backflow preventer come with shutoff valves?

No, this assembly is supplied without the shutoff valves. Users should install appropriate external isolation valves for their specific application.

What is ArmorTek® coating, and what are its benefits?

ArmorTek® is a patented 3-part advanced epoxy coating system applied to the ductile iron body. It is designed to significantly limit both microbial induced (MIC) corrosion and corrosion of exposed metal substrates, enhancing durability.

How does the SentryPlus Alert® flood sensor work?

The SentryPlus Alert® flood sensor is integrated into the assembly to detect continuous discharge from the relief valve. It can be paired with an add-on connection kit to relay alerts for potential flooding events to monitoring systems.

What materials are used for critical components in this assembly?

The assembly features a robust ductile iron body, a durable stainless-steel relief valve seat, and stainless-steel check components, all designed for maximum performance and extended valve life.
