An Air Release Valve is a type of valve used in water pipelines, irrigation systems, and industrial fluid systems to automatically release trapped air from the pipeline, ensuring smooth and efficient flow.
Key Features:
- Function: Releases accumulated air in the pipe system during filling or operation. Trapped air can reduce flow, create pressure surges (water hammer), or cause pipeline damage.
- Material: Often made from PVC, brass, or cast iron, depending on the pressure and application.
Operation:
- The valve opens when air accumulates at high points in the pipeline.
- It closes automatically when water replaces the air.
Size: Commonly available in ½", ¾", 1", or 2" sizes.
- Drip and sprinkler irrigation systems
- Main and sub-main water pipelines
- Overhead tanks and pump discharge lines
- Municipal water supply and industrial pipelines
- Prevents air-lock in pipelines
- Avoids pressure surges and damage
- Improves flow efficiency and system life
- Automatic operation, no manual handling required
