When water fills the pipeline, the valve rapidly expels trapped air. When the system drains, the valve draws in air to prevent vacuum formation and protect the pipeline from collapse or damage. Its advanced compound gas-dynamics design ensures fast, reliable air movement with minimal leakage even at low operating pressures.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n  \u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003cth style=\"text-align:left; padding:8px; border:1px solid #ddd;\"\u003eAttribute\u003c\/th\u003e\n\u003cth style=\"text-align:left; padding:8px; border:1px solid #ddd;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eProduct Name\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eAutomatic Air Vent Valve\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eConnection Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eBSPT External Thread (Female Connector)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eEntrance Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e20 mm \/ 0.79 in\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eOverall Size\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e35 × 20 mm \/ 1.38 × 0.79 in (H × OD)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003ePressure Level\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003ePN10 (Max \u0026lt;850 kPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eWorking Pressure Range\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e0.1 – 10 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eMax Working Temperature\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003e50°C (122°F) water temperature\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eHigh-Concern Chemicals\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd style=\"padding:8px; border:1px solid #ddd;\"\u003eMade in China\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 × Automatic Air Vent Valve\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eFor more information on irrigation system best practices and water efficiency, visit the \u003ca href=\"https:\/\/www.epa.gov\/watersense\/watering-tips\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eEPA WaterSense Watering Tips\u003c\/a\u003e page.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What irrigation systems is this automatic air vent valve compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: The APWIKOGER Automatic Air Vent Valve is suitable for a wide variety of garden and agricultural irrigation systems, including drip irrigation, sprinkler systems, and general pipeline setups that use standard BSPT external thread fittings with a 20 mm inlet connection.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the vacuum exhaust valve prevent pipeline damage?\u003c\/h4\u003e\n\u003cp\u003eA: When your irrigation system drains or shuts off, a vacuum can form inside the pipeline — creating negative pressure that may cause pipes or fittings to collapse or be damaged. This air vent valve automatically draws air into the pipeline to equalize pressure, preventing vacuum formation and protecting your irrigation infrastructure.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum operating pressure for this air vent valve?\u003c\/h4\u003e\n\u003cp\u003eA: This valve is rated PN10 and supports a working pressure range of 0.1 to 10 bar (maximum \u0026lt;850 kPa). It maintains a reliable seal at low pressures (as low as 0.3 bar) to prevent leakage across the full working range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this valve suitable for outdoor garden use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
