2-1/2 LF860 NRS RP

This 2-1/2 inch lead free MasterSeries® 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 backsiphonage 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 it is also used in irrigation systems, boiler feed, water lines and other health hazard installations requiring maximum protection. This assembly with non-rising stem shutoff valves consists of a lead free body, top mounted test cocks, spring loaded check valves, and a pressure differential relief valve. Improved with a stainless-steel relief valve seat, these rugged assemblies yield greater dependability and extended valve life. The coating on this backflow assembly uses ArmorTek®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
