It exhausts large volumes of trapped air when the irrigation system starts filling and re-admits air when the system shuts down, helping prevent water hammer, pressure surges, pipe collapse, and emitter suck-back. Unlike a combination valve, it is not designed for continuous release of small air bubbles while the system is pressurized.\u003c\/p\u003e\n\n\n\u003cp\u003e• SKU: 101045530\u003cbr\u003e\n• Brand: Rivulis\u003cbr\u003e\n• Valve Type: Air \u0026amp; Vacuum Release (Kinetic)\u003cbr\u003e\n• Connection: 1\" MPT (Male Pipe Thread)\u003cbr\u003e\n• Working Pressure: 0.10–10.0 bar (1.5–145 psi)\u003cbr\u003e\n• Maximum Operating Temperature: 60°C (140°F)\u003cbr\u003e\n• Body Material: Premium UV- and chemical-resistant resin\u003cbr\u003e\n• Pipe Compatibility: Metal and plastic pipe systems\u003cbr\u003e\n• Startup Function: Exhausts large volumes of trapped air as the pipeline fills\u003cbr\u003e\n• Shutdown Function: Re-admits air to break vacuum conditions\u003cbr\u003e\n• Water Hammer Protection: Helps reduce pressure surges caused by trapped air\u003cbr\u003e\n• Emitter Protection: Helps prevent substrate\/media particles from being sucked back through emitters\u003cbr\u003e\n• Sealing Pressure: Maintains a drip-tight seal at water pressures as low as 3 psi\u003cbr\u003e\n• Installation Point: Highest point of the irrigation zone or submain\u003cbr\u003e\n• Recommended Connection: Install into a 1\" FPT tee at the high point\u003cbr\u003e\n• Long Runs: Additional valves may be required at intermediate high points where elevation changes are significant\u003cbr\u003e\n• Continuous Air Release: No — not intended for removing small trapped air bubbles during pressurized operation\u003cbr\u003e\n• Chemical Resistance: Designed for agricultural fertigation; compatibility with aggressive cleaning chemicals should be verified before routine use\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The Rivulis Air \u0026amp; Vacuum Release Valve protects commercial irrigation zones from the large air and vacuum events that occur during repeated irrigation cycles, helping maintain hydraulic stability and preventing emitter suck-back.\u003c\/p\u003e","brand":"Hydro Supply Co.","offers":[{"title":"Default Title","offer_id":67610196836388,"sku":"RVLS-101045530","price":27.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0254\/3914\/1924\/files\/air-vacuum-release-valve.webp?v=1791317812","url":"https:\/\/www.growitdepot.com\/products\/rivulis-air-vacuum-release-mpt-1-air-valves","provider":"Grow It Depot","version":"1.0","type":"link"}
