What does constant pressure regulation of a control valve mean?

Is constant pressure the absolute pressure difference between the two ends?
I’ve never heard of constant pressure. Only the pressure before and after the valve and the pressure difference, or the primary pressure, secondary pressure, and pressure difference.
Having dealt with valves for so long, I’ve never really encountered the concept of fixed pressure. Could it refer to the rated pressure?
For PCV or PDCV, it’s the set value.
I understand it should be the set value of the control valve
