LF709NRSIOT LLC 10" CI DBL CV BF PRV

This 10 in. lead free double check valve backflow preventer assembly is designed to prevent the reverse flow of contaminated water of non-potable quality from being pumped or siphoned into the potable water supply due to back siphonage and or backpressure. 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, NRS resilient seated gate valves, test cocks, and a modular check design for easy maintenance with center stem guide. The captured spring is accessible through a bolted cover plate. This assembly features integrated pressure-sensing test cocks that measure pressure fluctuations at three points 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, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
