4 LF880V LG

This 4 inch lead free MasterSeries(R) configurable 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 is also used in irrigation systems, boiler feed, water lines and other health hazard installations requiring maximum protection. This assembly without the shutoff valves consists of a lead free body, 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.
