LF007-DOSY 2 1/2

This 2 1/2 inch lead free 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. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. 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 an fused epoxy coated cast iron body using ArmorTek(TM) coating technology for advanced corrosion resistance construction, domestic OSY resilient seated gate valves, top mounted test cocks, two in-line independent positive seating check modules, captured springs and replaceable check discs and seats. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
