dongfangs valve is OPEN when too low presser and CLOSED when too high.
Your valve can be half open and "almost closed" wich gives another type of actuation.

dongfangs thing will actuate to the right pressure very quickly but it might overflow a small bit because of piston reaction time.

your valve wont have that since when the desired pressure is nearly reached, the valve closes more and more, giving only a LITTLE flow wich makes the last part of the pressure regulation very slow.

Well, actually the other valve MIGHT be more accurate if its constructed very well and applied on a small chamber.
