- PROCESS VALVE
- Automatic Air Vent
An automatic air vent is a device used in heating and cooling systems to automatically remove air that becomes trapped in the system. As air is lighter than water or coolant, it can become trapped at high points in the system, which can cause problems such as reduced heat transfer, increased corrosion, and noisy operation. An automatic air vent typically consists of a small valve that opens when air is present and allows the air to escape from the system, while remaining closed when only fluid is present. This ensures that the system remains filled with fluid and free from air, which helps to maintain efficient and reliable operation.
