1/2 Inch Drip Irrigation Air Vacuum Relief Valve

Item No.: HT6505M

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.

To ensure optimal performance of a sub-surface installation, it is important to include an air relief valve. The valve will allow air to escape the pipeline, thus preventing water hammer or blockage. The valve will also allow air to enter the lines as water evacuates the lines at shutdown. This prevents vacuum suction of dirty water from occurring.
