Air release valves for waste water

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 used in sewage plants like waste water treatment plants, drains, etc.
