How should pressure be controlled in steam pipes to provide a supply ranging from 0.1MPA to 0.5MPA?

How can steam pipes be controlled to provide a variable pressure supply ranging from 0.1MPA to 0.5MPA? Or what kind of device should be used? A pressure relief valve can’t adjust the pressure automatically, right?
A pressure relief valve has to be used; there are self-regulating pressure relief valves available.
One pressure transmitter, one regulator, and one pressure relief valve are enough
If there are pressure transformers and control valves, then what’s the need for a pressure reducing valve?
Perhaps I didn’t explain myself clearly. What I’m referring to is a regulator, that is, a small computer that converts the electrical signals generated by pressure transducers into signals used to control the pressure reducing valve
Are there also pressure relief valves with automatic control? ?
Sure, modern pressure relief valves can all control their opening degree
Just use a pneumatic control valve, that’s it
