LF886WZ-LG-CFM 10

This 10 inch lead free MasterSeries(R) reduced pressure detector backflow preventer assembly is designed to prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. This valve features a longer lay-length for drop-in replacement of competitor?s Z-pattern valves. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. It is used primarily on standpipe systems and fire sprinkler requiring detection of unauthorized water use. The assembly without shutoff valves consists of a ductile iron body, cubic feet per minute metered bypass, replaceable stainless steel check seats, and ball valve test cocks. Improved with a stainless-steel relief valve seat, these rugged assemblies yield greater dependability and extended valve life.
