The AVG dual check valve 2NV is designed to prevent cross contamination of non-potable water into safe drinking water. The two spring loaded check valves remain tightly closed until there is a demand for water downstream. In the event that there is reverse of flow direction, the check valves will close and backflow is prevented. The AVG models 2NV20-20F, 2NV20-20FM and 2NV25-25F dual check valves provide protection in low hazard applications, like meter connections on domestic properties.
