FAQs

What is the primary function of the FEBCO LF870V Double Check Valve Assembly?

The primary function is to prevent backflow of non-health hazard (pollutant) substances into a potable drinking water system, protecting against conditions of backpressure and backsiphonage.

What material is the main valve body made from, and how is it protected?

The main valve body is constructed from ductile iron (Grade 65-45-12) and is protected with ArmorTek®, a patented three-part advanced epoxy coating system designed to resist microbial-induced corrosion (MIC) and protect exposed metal.

What are the acceptable installation orientations for this backflow preventer?

This assembly is approved for both horizontal (N-pattern) and vertical-up (Z-pattern) installations, providing flexibility for different site requirements.

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

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).

Are special tools required for servicing the check modules?

No, servicing of both check modules does not require any special tools. They can be accessed through independent top entry covers for convenience.
