Double Chamber Air Release and Vacuum Valves are designed to perform three functions:
1. Venting of large volumes of air on the start-up of the system, while pipelines are filled.
2. Intake of large volumes of air on shut-off of the system, while pipelines are being drained.
3. Discharge of pressurized air pockets during the operation.
