The Atmospheric Vacuum Breaker is designed to prevent contaminants from entering the main water supply through sprinkler heads. It is not designed to be used as a mainline anti-siphon device.

The Dual Check Valves provide cost-effective backflow protection of the public water supply. This model can be installed in a variety of piping configurations, and in conjunction with a wide range of meter horns, copper setters, and meter boxes.

The straight line, poppet-type construction of this model minimizes pressure drop and provides smooth flow characteristics. It can be installed horizontally or vertically. It is not adversely affected by normal line pressure surges, will not cause water hammer, and operates without chatter or vibration. Maximum Working Pressure: 150psi (10.3 bar).
