Double Check Valve Assembly, 3/4 Inch, Lead Free, Quarter Turn Shutoff, Single Top Entry, Freeze Sensor, Series 007M3

This 3/4 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 back siphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications, at cross-connections identified as non-health hazards, and for the service line entrance contaminants. This assembly consists of a lead-free cast copper silicon alloy body construction, NPT end connections, quarter turn ball valve shutoffs, top-mounted test cocks, two in-line independent positive seating check modules, captured springs, and replaceable check discs and seats. The double check valve includes a freeze sensor for use with SentryPlus Alert^® technology to signal facility personnel when temperature nears and reaches the freezing point. Freeze alerts feature available with an add-on connection kit for Wi-Fi networks, building management systems (BMS), and irrigation management systems (IMS).
