Additional Details

The 3 inch Febco LF870V Double Check Valve Assembly with Non-Rising Stem (NRS) gate valves is designed to protect potable water systems from backpressure and backsiphonage conditions caused by non-health hazard (pollutant) backflow.

This assembly is ideal for containing objectionable but non-toxic pollutants at the service line entrance or for non-health hazard cross-connections.

Key Features

  • Lead Free* construction, with wetted surfaces containing less than 0.25% lead by weight, complies with low lead installation requirements.
  • Utilizes ArmorTek® coating technology, a patented three-part advanced epoxy system applied to internal and external surfaces, to reduce microbial-induced corrosion (MIC) and protect exposed metal substrates.
  • Features an in-line serviceable design with top-entry covers for both check modules, requiring no special tools for maintenance.
  • Equipped with two (2) independently acting, approved clapper style check modules with replaceable seats and disc rubbers.
  • Configurable for both Horizontal (N-pattern) and Vertical Up (Z-pattern) installations; shipped in standard N-pattern.
  • Includes stainless steel check components, captured modular spring assembly, and field replaceable seats.
  • Designed with a ductile iron valve body and ball valve test cocks.

Inquire with governing authorities for local installation requirements prior to installation.
