Finding the 4-Way 2-Position Directional Valve (2P) Block

I am currently using the 2024 version and have been looking in the library as well as the search up and I am not able to find this block. Please let me know how I can access it. Thank you!

Hi @Vanessa Mendez-Valencia,

After reviewing the documentation provided at the link below

https://www.mathworks.com/help/hydro/ref/4way2positiondirectionalvalveil.html

It should be located under Libraries: Simscape / Fluids / Isothermal Liquid / Valves & Orifices / Directional Control Valves

[Vanessa]

I have attached the block i was refering to, it is specifically for two-phase fluids

Hi @ Vanessa Mendez-Valencia,

If you notice @Walter Roberson has pointed out a good point.

[Walter Roberson]

It is in Simscape Fluids, since R2021a.

[Walter Roberson]

What you attached says it is since R2024b, but you indicated that you are using R2024a.

Indeed, it's available starting R2024b. There is a new reversible heat pump example that is using this block.

For earlier versions, one may use a few orifice (2P) components and PS lookup tables to build a behavioral 4 way valve.

Thank you!
