Adjust a Pressure Reducing Valve?

Hallo,

how can I adjust some given pressure with one Valve.

The "Pressure Reducing Valve" can only adjust one pressure, but I need a Valve for adjustable pressure.

How can I do that?

Thanks for yout help and sorry for my bad english :)

I am guessing, you are trying to build a valve block that will achieve any given pressure at its outlet?

I think the best way to model the "behavior" of this valve is to add some control elements to a variable orifice. The orifice will open wider if the outlet pressure is too high, and vice versa.

If the set pressure comes from a pilot pressure signal, you can also use valve actuator blocks to reference the outlet valve pressure, so at equilibrium, the outlet pressure will match the pilot command.

Sorry I am making lots of assumption with my answer. More clarification on the question would help.
