3/4" MPT Air Vacuum Relief Valve

Product Description
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.Product DetailsDual acting air release & vacuum relief valveMaximum working pressure: 80 psiInlet 3/4" pipe threadSeals at 5 psiClear open diameter is 0.610"UV stabilized, durable, weather resistant and engineered plasticsBright colors for easy visibilityRemovable top for easy seal maintenanceHeight: 5.01 inchesWidth: 1.81 inchesWeight: .21 lbs
