Hi, I am modeling a revversible refrigeration cycle on simulink. My school has not updated the computers to the 2024b version so i am not able to use the 4way-2position directional valve for a two-phase liquid. Does anyone know how to model this using orfices? I know it is possible, I'm just not sure where to start or how to go about it.
Thank you!

Hi @Vanessa Mendez-Valencia
The 4-way two position valve can be created using the 'Orifice(2P)' block.The example in the following link demonstrates how to implement a 4-way valve:
https://in.mathworks.com/help/simscape/ug/hydraulic-actuator-with-analog-position-controller-il.html#d126e38921
In this example, the 'Spool Valve' subsystem implements the valve using the 'Local Restriction (IL)' block, which can be replaced with the 'Orifice (2P)' block.
I hope this helps!
