• 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
• Configurable N-Pattern design
• Lead free construction

This 2 1/2 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 assembly with non-rising stem 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 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.
