It combines a manual valve with an atmospheric vacuum breaker to stop backflow contamination in culinary water systems. Turn the handle or use a sprinkler key for direct flow adjustments without external controllers.\u003c\/p\u003e\n\u003cp\u003eThe unit handles up to 80 PSI for active zone control. Its poppet and seal mechanism relies on pressure drops to release trapped air, meaning constant pressurization must stay under twelve hours daily. Extended continuous flow risks seal adhesion that blocks the atmospheric vent. Use this valve for scheduled irrigation cycles instead of permanent mainlines.\u003c\/p\u003e\n\u003ch3\u003e📋 Product summary:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e3\/4 inch sizing with manual actuation\u003c\/li\u003e \u003cli\u003eAtmospheric vacuum breaker safeguards culinary water from backflow\u003c\/li\u003e \u003cli\u003eHand-operated flow control compatible with standard sprinkler keys\u003c\/li\u003e \u003cli\u003eMaximum operating pressure of 80 PSI\u003c\/li\u003e \u003cli\u003ePoppet and seal design requires daily unpressurized intervals beyond twelve hours\u003c\/li\u003e \u003cli\u003eEngineered for routine zone cycling rather than continuous mainline service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Orbit Irrigation","offers":[{"title":"Default Title","offer_id":46532360732868,"sku":"51016","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/5971\/6548\/files\/51016wpath_f5aa1520-039e-454b-8664-1bf6b6634e5e.jpg?v=1786910381","url":"https:\/\/shop.soil911.com\/fr\/products\/3-4-inch-fpt-manual-anti-siphon-sprinkler-valves-51016","provider":"Tampa Home \u0026 Garden Store","version":"1.0","type":"link"}
