1. A pressure regulating system for a beverage container system, comprising a first compartment for containing a pressurized gas, in fluid communication with a surrounding space through at least a gas valve for opening and closing a passage between the first compartment and surrounding space, wherein a gas valve control system is provided, comprising a deformable and/or movable wall or wall part, wherein said deformable and/or movable wall part is operably in contact with the at least a gas valve for opening and/or closing the at least a gas valve, wherein a second compartment is provided at a side of said deformable and/or movable wall part, said movable and/or deformable wall part forming a wall of said second compartment, wherein the second compartment forms a pressure regulating space and comprises a wall part formed by or comprising at least a gas permeable wall part, wherein the at least a gas permeable wall part is liquid tight and stiff such that the at least a gas permeable wall part will not deform when there is a pressure difference over the at least a gas permeable wall part, and wherein the at least a gas permeable wall part has a gas permeability in the range of 1000 to 4000 barrer, the gas permeability being given for CO2 gas or N2 gas or a CO2/N2 gas mixture.
