Abstract:
A method for withdrawing a pressurized gas from a receptacle comprising a tap, the tap comprising a filler/withdrawal coupling for a pressurized gas receptacle designed to interact with a packaging connector in order to allow said receptacle to be filled with pressurized gas or for withdrawal of pressurized gas from the receptacle, the method comprising a) a first step of moving a dust-prevention valve downstream in order to open the upstream end of the circuit via a mechanical actuation and/or a fluidic actuation carried out by the packaging connector and b) a second step of moving an isolation valve to a downstream opening position via a mechanical actuation carried out by the dust-prevention valve and/or via a fluidic actuation carried out by the gas delivered by the packaging connector.
