It features a cast iron body. Rated to 175 psi. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 8 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. This assembly consists of an fused epoxy coated cast iron body, domestic NRS 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 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePressure sensors integrated on the backflow preventer to measure pressure fluctuations at three test cock locations when activated\u003c\/li\u003e\n\u003cli\u003eAdd-on kit available for activating sensors and transmitting data values to a building management system\u003c\/li\u003e\n\u003cli\u003eA solution for monitoring assembly performance between code testing\u003c\/li\u003e\n\u003cli\u003eData access to help drive scheduling of maintenance and repair\u003c\/li\u003e\n\u003cli\u003eUtilizes advanced ArmorTek coating technology to resist corrosion of internals\u003c\/li\u003e\n\u003cli\u003eCast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion\u003c\/li\u003e\n\u003cli\u003eDomestic non-rising stem gate valves\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this Double Check approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for low health hazard (non-toxic, \"pollutant\") cross-connections only.
