This 2 1/2" 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 cross-connections identified as non-health hazards. This assembly consists of an fused epoxy coated cast iron body, non-rising stem resilient seated gate valves, top mounted test cocks, two in-line independent positive seating check modules, captured springs, and replaceable check discs and seats. This assembly features integrated pressure-sensing test cocks that measure pressure fluctuations at three points on the backflow preventer when activated with an add-on monitoring connection kit. The kit collects, converts, and transmits the data values for use in a building management system. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.
