Dripline Air Vacuum Relief Valve

Albert Montano Sand and Gravel, a Santa Fe, NM, drip irrigation product supply company, now carries dripline air vacuum relief valves. DIG’s 1/2″ Air Vacuum Relief Valve with male pipe thread delivers optimum performance and increased efficiency of a drip system by preventing back suctioning of debris into the drip line. The relief valve allows air to escape the drip line during the system’s initial start and until the pipe or drip line is full of water. It also allows air to enter back into the drip line when the drip zone is turned off. The Air Vacuum Relief Valve helps prevent clogging in sub-surface drip irrigation systems resulting from back suction of debris under vacuum conditions. Install the valve at the highest point of a drip line installation.
