How should the pressure setting range of a self-acting control valve be selected? For example: for a nitrogen pipeline with an operating pressure of 300 kPa, a pressure drop of 290 kPa, and an outlet pressure set at 10 kPa, what should be the setting range? For example: instrument air, operating pressure 650 kPa, pressure drop

How to select the pressure setting range for a self-acting control valve
The set pressure is the outlet pressure.
There is no such thing as a \"pressure setting range for self-acting control valves\"; what exists is only the \"set pressure\", which is the pressure that the self-acting control valve is intended to regulate.
