How fast the pressure change

I have a pressurized pipe (230bar) which is opened to a way lower pressure tube (1 bar) through a valve. the pipe is filled with 2phase flow (gas and oil). I am looking for an explanation or formulation on how fast the pressure drops upstream the valve. I know pressure equation is of parabolic nature and parabolic equation has the property that the information propagates at arbitrary high speed.
Any reference or explanation is very much appreciated.
