For an orifice plate, when the pressure in front of the orifice plate increases, does the pressure behind it also increase?

I’m confused about everything I discuss with others.
It is the case within a certain range; once it exceeds the speed of sound, it becomes stable.
Generally, this is the case: the flow-limiting effect of the orifice plate is not that strong; it should be the same in all situations. The so-called sound speed limit generally refers to the flow control orifice plate.
The measurement orifice plate should not exceed the speed of sound.
When the operating conditions remain unchanged (i.e., the load stays constant), an increase in pressure before the orifice plate will also result in an increase in pressure behind it. If the load increases at this time, however, the pressure behind the orifice plate may decrease.
