4 In Cast Iron Double Check Valve Assembly Backflow Preventer, Domestic NRS Shutoffs, Strainer, Epoxy Coated Using ArmorTek Technology
This 4 inch double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for other non-toxic contaminants at the service line entrance. This assembly consists of a fused epoxy coated cast iron body, domestic non-rising stem resilient seated gate valves, top mounted test cocks, two in-line independent positive seating check modules, captured springs, replaceable check discs and seats, and cast iron strainer. The coating on this backflow assembly uses ArmorTek(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
