Air Release & Vacuum Valves for Sewage are designed to perform three functions in a single body for use in wastewater/ sewage systems:
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.
Due to its special sealing mechanism, the air valve does not get plugged and can operate in liquids with particles.
