Air vent valves are valves installed in pipeline systems to release air and other gases. They are typically installed at high points in the pipeline to quickly release gases and prevent the formation of air pockets that could affect the normal operation of the pipeline.
When should air vent valves be closed? Air vent valves should be closed when their function is no longer needed, such as when all gases have been released from the pipeline system, or when maintenance or replacement of the air vent valve is required during system operation.
Air vent valves have a wide range of applications, commonly found in water supply, gas supply, chemical, and food processing industries. In these fields, the installation of air vent valves can improve the operational efficiency and safety of the pipeline system.
