Frequently Asked Questions
What is an air release valve?
An air release valve is a plumbing or irrigation component designed to automatically release trapped air from pipelines, helping maintain proper flow and system efficiency.
What is the purpose of an air release valve?
An air release valve helps:
- Remove trapped air from pipelines
- Prevent air locking
- Improve water flow efficiency
- Protect pipes and system components
- Reduce pressure-related issues
How does an air release valve work?
The valve detects accumulated air inside a pipeline and automatically opens to release the trapped air. Once the air is removed, the valve closes to prevent water leakage.
Where are air release valves used?
Air release valves are commonly used in:
- Irrigation systems
- Water supply pipelines
- Agricultural fertigation systems
- Industrial piping systems
- Pumping systems
What types of air release valves are available?

What is the difference between an air release valve and an air vacuum valve?
An air release valve removes accumulated air during normal operation, while an air vacuum valve allows large amounts of air to enter or exit during pipeline filling, draining, or pressure changes.
Can air release valves be used with fertilizers?
Yes. For fertigation systems, select valves made from materials compatible with the fertilizer solution being used.
Are air release valves easy to install?
Yes. Most models are designed for straightforward installation using standard pipe fittings and connectors.
What are the benefits of using an air release valve?
Benefits include:
- Better pipeline efficiency
- Improved irrigation uniformity
