Abstract
A device for controlling a liquid flow by a gas pressure. The device includes a pressure chamber, in which an overpressure, an underpressure or atmospheric pressure may prevail. The pressure in the pressure chamber can be used for allowing the liquid flow to pass or for stopping the liquid flow. Furthermore the liquid flow can be limited to a predetermined rate of flow. The device may interalia be used in sewage systems, hydraulic engineering works and irrigation works.
