FEBCO LF860 Reduced Pressure Zone Assembly 3 in. Lead Free with NRS Gate Valves

This 3 inch lead free MasterSeries(R) reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of high hazard (toxic) fluids found in the water from entering into the potable water supply due to back siphonage and or backpressure in accordance with national plumbing codes and water authority requirements. It is used in industrial plants, hospitals, morgues, mortuaries, and chemical plants and is also used in irrigation systems, boiler feed, water lines and other installations requiring maximum protection. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and for contaminants at the service line entrance. This assembly consists of an epoxy coated ductile iron body, domestic non-rising stem resilient seated gate valves, test cocks, spring loaded check valves, and a pressure differential relief valve. The ductile iron body is fused with ArmorTek(TM) coating technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. Improved with a stainless-steel relief valve seat, these rugged assemblies yield greater dependability and extended valve life.
