How to model a Electronic Proportional Control Valve

I am using a VSO LowPro Proportional control Valve (https://www.parker.com/Literature/Precision%20Fluidics/Miniature%20Proportional%20Valves/VSO%20LowPro.pdf) to regulate pressure into a closed actuator.

I am wanting to try and model this system in simulink but I am unsure on how to model this valve. I have done circuit modeling of electrical systems but not electrical mechanical systems and general you can get the transfer function from the response of the system. However could you use flow rate vs pressure to model the system?

Any help of this would be greatly appreciated.

Cheers

• It depends on how simple or complex the model should be. The data sheet gives a 'response time' of 10 ms, which I take to be the steady-state response time, in which case a first order exponential with $\tau = \small 10/5 = 2 ms$, along with a constant gain, might suffice. – Chu May 5 '19 at 8:55
