An air admittance valve is a one way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system. The device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAir Admittance Valve\u003c\/li\u003e\n\u003cli\u003eSchedule 40 - 160 DFU\u003c\/li\u003e\n\u003cli\u003eApproved for up to 4\" pipe\u003c\/li\u003e\n\u003cli\u003eUse as an air inlet source or a secondary vent\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Oatey","offers":[{"title":"Default Title","offer_id":46330754433159,"sku":"EJD4305041","price":35.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/0774\/7207\/files\/4305041.jpg?v=1793085448"}],"url":"https:\/\/www.storeseven.com\/collections\/pressure-regulator-valves-air-admittance-valve.oembed","provider":"StoreSeven","version":"1.0","type":"link"}
