3 In Cast Iron Double Check Detector Assembly Backflow Preventer with Domestic OSY Shutoffs, Cubic Feet Meter, 3/4 In Bypass, ArmorTek Coating
This 3 inch double check 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. It is ideal for protection at cross-connections identified as non-health hazards such as on fire protection systems and from other contaminants found at the service line entrance. It consists of a fused epoxy coated cast iron body using ArmorTek(TM) coating technology for advanced corrosion resistance construction, domestic outside stem and yoke resilient seated gate valves, captured spring check valves, a cubic feet per minute metered 3/4 inch bypass to detect underground leaks and unauthorized water use, and four test cocks. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
Features
- Utilizes advanced ArmorTek coating technology to resist corrosion of internals
- The valve body shall utilize a coating system with built in electrochemical corrosion inhibitor and microbial inhibitor
