ABSTRACT:
A controlled valve with automatic opening and an aircraft having a valve of this type. The controlled valve enables the regulation of pressures or flow rates. Furthermore, the control valve can open autonomously under the effect of a pressure difference exceeding a pre-determined threshold. Thus, it enables fast balancing of pressures if the pressure difference should exceed a threshold beyond which, for example, an installation may be put in danger. The controlled valve can be applied to any device for the regulation of pressure and/or flow rate between a chamber and the exterior or between two chambers having a safety balancing device. The disclosure can be applied notably in aeronautical construction, the construction of petroleum refineries, of fluid distribution devices and of chemical reactors.
