(Part Number: AVRV 50) – 1/2 in. MPT Air/Vacuum Release Valve – 25-Pack – Valves – Valves for Flowerpot Irrigation Systems – Reliable Water Flow Control – Made in America – NDS

Key Features

• 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
• Automatic flush valve keeps the line free of dirt and debris and helps prevent mineral buildup; makes it easy to flush out the line; when water pressure drops, the valve automatically opens to drain the line, closes when done to keep bugs out
• Ball valve helps control the water flow; easy to shut off water or allow it to flow through by turning lever that rotates the ball inside to open or close line
• Flow control valve delivers two varying water flows to two separate watering circuits, irrigation zones, or plants with different watering needs; turn dial to adjust, balance, or shut off water

Applications

• Manage the flow of water in the pipeline with a variety of valves to release trapped air; flush out the line; control water flow; manage water flows to two separate zones
• Air/vacuum release valve for subsurface drip systems; other valves for on grade or subsurface installation
• As part of a complete drip irrigation system, valves control the flow of water to the area to be irrigated

Materials & Sustainability

• Flow control valve made of acrylonitrile Butadiene Styrene (ABS) treated with UV inhibitors to prevent cracking
• Drip irrigation can reduce water usage by up to 70% compared to conventional sprinkler irrigation when used properly; for most drip irrigation products, water is applied precisely and at the rate the soil can accept it to prevent runoff and erosion

Installation & Maintenance

• Air/vacuum valve: 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
• With the exception of the air/vacuum valve, valve can be installed between two lengths of pipe or tubing where the flow of water needs to be controlled
• Periodically check for leaks or damage and replace or repair as needed; recommended operating pressure is up to 50 PSI
