WATTS 88003389 LF709-NRS-IOT 6 DOUBLE CHECK VALVE BACKFLOW PREVENTER

WATTS®, 88003389, Backflow Preventer, Inline, Series: LF709, 6 in Nominal, Flange Joint End Style, 175 psi Pressure, 33 to 140 deg F, 7.5 fps Flow Rate, Non-Rising Stem Resilient Seated Gate Valve Ball Valve/Gate Valve, Media: Water, Cast Iron Body, Epoxy Coated, Domestic

This 6 inch 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 backsiphonage 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(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
