SimHydraulic + Pressure Relief Valve

Good Morning,

I'm using SimHydraulics. It's possible create a Pressure Relief Valve that have a tunable parameter (like Valve Pressure Setting) ?

Thanks, João Ivo

Simscape and SimHydraulics parameters are not tunable. What's the application and intended use?

The equations for the Pressure Relief Valve block are provided in the documentation for the block, so you could potentially write your own version using the Simscape language, where you would have the Valve Pressure Setting as an input rather than a parameter. However, I am not sure this corresponds to anything physical.

Hi

I also have this doubt too. I'm trying to mount a pressure control system in closed loop using the pressure relief proportional valve. Do you have some examples?

I'm using the valve link below.

Thanks.

Thanks Arnaud,

I'll follow these Simscape language tutorial. The intended is to simulate a variable Pressure Relief Valve.
