The Watts Bronze Freeze-Resistant Pressure Vacuum Breaker Backflow Preventer Assembly with Freeze Sensor provides the ultimate mechanical protection against cross-connection hazards. Engineered to prevent the backflow of polluted water from entering into the potable water supply due to back-siphonage and backpressure, this assembly stands as a steadfast barrier, ensuring the purity of potable water.
Featuring a comprehensive array of features, this assembly is constructed with a highly durable bronze body, ensuring long-lasting performance. It is equipped with a silicone rubber check valve disc, plastic check valve seat, female NPT inlet and outlet with quarter turn shutoffs, stainless steel springs, a bonnet with silicone rubber O-ring seal, a lightweight plastic disc float, a unique built-in relief valve that relieves pressure caused by ice formation and protects internal components from freezing, tee handle shutoffs, and test cocks for winterization draining. Additionally, it has a freeze sensor compatible with SentryPlus Alert technology, signaling facility personnel when temperatures near and reach freezing point. For added assurance, an optional freeze sensor connection kit is available to activate a monitoring system for low and freezing temperatures, ensuring that your water supply remains safe and secure.
Designed with practicality in mind, this assembly has internal parts that are serviceable in-line from the top of the unit for easy maintenance. It is ideal in continuous pressure applications such as irrigation systems and industrial process water systems where water enters the equipment at or below its flood rim, as well as in hospitals, morgues, mortuaries, chemical plants, boiler feeds, water lines, and other key systems.
