Pressure relief valve

Pressure relief valve

Can anyone advise me on how to add a pressure relief valve for a fluid system into a model, using the Modelica Standard Library? It will pick up from the pump discharge side and return the flow to the suction side.

Thanks,

Calum

Hello,
it is a bit older post, but I have the same question. Have you found a way to do it?
Many thanks / greetings

Re: Pressure relief valve

I think you can use IncompressibleValve and use input port to set valve opening as pressure changes.

Re: Pressure relief valve

Hello!
Thank you very much for the help. There are different ways to solve it, depending on the requirements. In my case, I solved it with a valve for compressible media and a relative pressure measurement via the valve. The relative pressure measurement then passed the value to a hysteresis and a switch opened or closed the valve. In my case, however, it only worked when I set filterOpening=true for the valve.
