How to represent Globe Valves and Butterfly Valves?

I am working on a Simulink model of a turbine (I have never learned SImulink before, and I have only about 2 weeks and a half of practice), where the fluid (air) comes through a pipe system and different types of valves. I am a bit confused regarding two valves: the globe and the buttefly valves. Which blocks in Simulink can help me represent these two components? I have thought about using the 2-way Directional Vavle block as my globe valve, and the closest thing I found was the Gate Valve block as my butterfly valve. However, I am unsure about this. Could someone give me some suggestions?
I thank you very much for all your help!
Kind regards,
Isaac L.

Hi Isaac, thanks for responding so many years later! Do you have an example of using the variable orifice for butterfly valve simulation with PID control? I cannot find a good example on how to model it.

Hi,
In Simulink, there are several blocks you can use to represent valves in your turbine model, including the globe valve and butterfly valve. Here are some suggestions:
- Globe Valve: The 2-way Directional Valve block can indeed be a suitable choice for representing a globe valve. This block allows you to control the flow direction based on an input signal. By appropriately setting the input signal, you can simulate the opening and closing behavior of a globe valve.
- Butterfly Valve: While there is no specific "Butterfly Valve" block in Simulink, you can use other blocks to represent its functionality. One option is to use a variable orifice block, such as the Variable Orifice block or Variable Area Orifice block. These blocks allow you to control the size of the orifice opening, simulating the behavior of a butterfly valve.
