The FEBCO Series 765 Pressure Vacuum Breakers are designed for non-health hazard applications, providing protection against backsiphonage of both toxic and non-toxic liquids in various settings such as industrial plants, cooling towers, laboratories, laundries, swimming pools, and lawn sprinkler systems. The units are available in sizes ranging from 1/2" to 2" (15mm to 50mm) and feature a durable bronze body, a spring-loaded check valve, and an air relief valve that operates at 1psi to prevent siphoning. These assemblies are engineered for minimal head loss and include serviceable internal parts accessible from the top. They are rated for a maximum working pressure of 150psi (10.3 bar) and can handle water temperatures from 32¬8F to 140¬8F (0¬8C to 60¬8C). The design incorporates freeze protection features, including an engineered plastic bonnet and optional union end ball valves for easy removal. It is important to note that this product is not legal for use in plumbing systems supplying water for human consumption in the United States.
