An aircraft gas transport system (110) includes a high pressure gas supply line (115) having a supply valve (120). The gas transport system also includes an equilibrium gas line (150) joined at junctions with the high pressure gas supply line upstream and downstream from the supply valve, and in flow communication with the high pressure gas supply line. The equilibrium gas line has an equilibrium valve (140) and a flow restrictor (135). The equilibrium valve has an exit orifice (173), and the flow restrictor is offset from the exit orifice of the equilibrium valve. A method for pressurizing a gas transport system (110) after a flow of gas through the gas transport system has been prevented (400) comprises: opening (410) an equilibrium valve (140) while maintaining a supply valve (120) closed to allow a flow of gas (GFA) through a flow restrictor (135) that controls a rate of change of a pressure downstream of the equilibrium valve; determining (420) that the pressure downstream of the equilibrium valve or supply valve is stabilized; and opening (430) the supply valve to provide a flow of gas (GFB) through the supply valve at an operating pressure.
