ASSEbackflow preventer

This 1/2 inch dual check valve backflow preventer with intermediate atmospheric vent helps prevent the reverse flow of hot or cold polluted water from entering into the potable water supply. This valve is designed for continuous pressure non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. It consists of a brass body with stainless steel internal parts, integral strainer, two durable tight seating rubber check valves, and soldered end connections.

The primary purpose of a pressure or vacuum relief valve is to protect life and property by venting process fluid from an over pressurized vessel or adding fluid (such as air) to prevent formation of a vacuum strong enough to cause a storage tank to collapse. Proper sizing, selection, manufacture, assembly, testing, installation, and maintenance of a pressure relief valve are all critical for optimal protection of the vessel or system.
