Double Ball Air Release Valve
Product Description: A double ball air release valve is a type of valve used in fluid systems to release air or gas pockets from the system while preventing the entry of liquid. It is commonly employed in pipelines, water distribution networks, and other fluid handling applications to maintain efficient operation and prevent issues such as air locking or pressure surges.
Fields of Application: At pump outputs, at the peak of pipeline, every 500 meters on flat pipeline.
Pressure Class: PN10-PN16-PN25-PN40.
Body: At AccessX the body of this type of valve is available in Ductile Iron (GGG40) etc.
Operation: The double ball air release valve functions based on the difference in density between air and liquid. When the system is initially filled with liquid, air or gas pockets are present within the pipeline. As liquid enters the valve chamber, the buoyant sealing balls rise to the top of their respective chambers, allowing the air or gas to escape through the valve's vent.
Relevant Standards: EN 1074-4, EN 1092-2.
Paint: WRAS approved blue electrostatic epoxy powder paint (RAL 5005).
