NDS Air/Vacuum Release Valves

Air/Vacuum Release Valve

Air/vacuum release valve helps prevent damage to the drip system due to water hammer and cavitation; releases trapped air and allows water to flow through; when water escapes, fills void with air to prevent vacuum suctioning of debris into the line

Key Benefits

Helps prevent debris from being suctioned into the drip system
Releases trapped air and allows water to flow through

Applications

Install upright on a high point in the drip system, on top of pipe riser with 1/2 in. FPT connection point; use on line that runs perpendicular to lateral rows, before and after steep slopes, and on long, horizontal runs; protect with a valve box

Materials & Sustainability

ABS (Acrylonitrile Butadiene Styrene) treated with UV inhibitors to prevent fading and cracking
