• Ductile iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion
• Combines the use of a stainless-steel relief valve seat and stainless-steel check components for maximum performance and durability
• Detector bypass assembly
• Appropriate for health hazard applications

This 6 inch lead free MasterSeries(R) reduced pressure detector backflow preventer assembly help protect against high hazard (toxic) fluids in water services to industrial installations and applications. This assembly without shutoff valves consists of a ductile iron body, replaceable stainless steel check seats, cubic feet per minute metered bypass, and ball valve test cocks. The ductile iron body is fused with patented 3-part ArmorTek(R) epoxy coating for advanced corrosion resistance. 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. 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.
