After the pipeline downstream of the pressure reducing valve is cut off, does the pressure behind the valve remain at the set reduced pressure, or does it become equal to the pressure before the valve?

Dear sea friends, after the pipeline downstream of the pressure reducing valve is shut off, will the pressure behind the valve remain at the set reduced pressure, or will it become equal to the pressure before the valve?
Maintain the set pressure after depressurization
It gets close to the pressure before the valve; after it is shut off, the pressure regulator cannot adjust that quickly.
