DT-ARV100 - 1" MPT Air Vacuum Relief Valve
Air Release & Vacuum Relief Valves are installed on the highest point of a drip irrigation or drip tape watering system to minimize the collapse of mainline and submain pipes, and reduce back siphonage of dirt into drip emitters and drip tape. A rapid drop in line pressure can cause tubes to collapse or flatten. In a newly installed system, loose soil may settle around a collapsed tube, making it difficult for the tube to regain its shape when the next irrigation cycle begins.
Air release valves also reduce the chance of water hammer caused by a sudden reversal of water flows. They allow air to escape during system start-up and prevent air restrictions. Trapped air bubbles can damage pumps (via cavitation) and disrupt flow rates and pressure.
