LF880W-DNRS-FS 4

This 4 inch lead free MasterSeries(R) configurable reduced pressure zone backflow preventer assembly help protect against high hazard (toxic) fluids in water services to industrial installations and applications. This valve features a longer lay-length for drop-in replacement of competitor?s N-pattern valves. This assembly with domestic non-rising stem shutoff valves consists of a lead free body, 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. This backflow assembly contains a flood sensor with SentryPlus Alert(R) technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor can send an alert to notify personnel about potential flooding. Add-on sensor connection kits are available for BMS and cellular communications.
