Air release valves can have many functions, the main one being the discharge of pressurized air pockets during the operation. They can also allow air to escape at high speed when filled with water and let air back in at high speed in the event of the piping being drained. They are mainly used in piped water supplies.

APPLICATION

General use :

1. Disposal of large volumes of air during fill of the pipes of system.

2. Add great amount of air to the system during the purge of the pipes.

3. Release of pressurized air pockets during operation.

4. Discharge of the small bubbles of air that are located in the top of the pipes

to improve the circulation of the fluid.
