Febco F683106 4 IN Lead Free Reduced Pressure Zone Backflow Preventer Assembly

This 4 inch lead free MasterSeries® reduced pressure zone backflow preventer assembly help protect against high hazard (toxic) fluids in water services to industrial installations and applications. 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™ 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. This backflow assembly contains an integrated flood sensor with SentryPlus Alert® 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.
