Automatic Air Vent Valve for Garden Irrigation Systems
Automatic Air Vent Valve for Garden Irrigation Systems
APWIKOGER Automatic Air Vent Valve – Vacuum Exhaust & Intake for Irrigation Systems
Keep your irrigation system running at peak efficiency with the APWIKOGER Automatic Air Vent Valve. This compact, durable plastic air vent valve is engineered for garden and agricultural irrigation pipelines, automatically discharging trapped air during water fill and drawing air back in during drainage — preventing vacuum negative pressure that can damage your pipes and fittings.
Key Features
- Compact & Reliable: Small footprint with a simple, dependable structure that fits easily into any irrigation setup.
- Direct Passage Design: Large inlet and outlet openings maximize airflow and water flow, reducing pressure loss.
- Long-Stroke Sealed Float: Prevents high-velocity air from prematurely closing the valve, ensuring complete air discharge and intake every cycle.
- Dynamic Low-Pressure Seal: Maintains excellent tightness at low operating pressures (as low as 0.3 bar) to prevent leakage.
- Corrosion-Resistant Components: All parts are corrosion-resistant for low maintenance and extended service life.
- Dustproof & Waterproof Breather: Protected against dust and moisture ingress for reliable outdoor performance.
- BSPT External Thread Connection: Standard thread form for easy, secure fitting into existing pipelines.
How It Works
The vacuum intake and exhaust valve is a power-type quick-response valve suitable for a wide range of irrigation systems. 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.

Frequently Asked Questions
Q: What irrigation systems is this automatic air vent valve compatible with?
A: 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.
Q: How does the vacuum exhaust valve prevent pipeline damage?
A: 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.
Q: What is the maximum operating pressure for this air vent valve?
A: This valve is rated PN10 and supports a working pressure range of 0.1 to 10 bar (maximum <850 kPa). It maintains a reliable seal at low pressures (as low as 0.3 bar) to prevent leakage across the full working range.
Q: Is this valve suitable for outdoor garden use?
A: Yes. The valve features a dustproof and waterproof breather design, making it well-suited for outdoor garden irrigation installations. All components are corrosion-resistant, ensuring durability and low maintenance even in typical outdoor conditions.
