Hi guys,
I'd like to use an Arduino to control a 24V proportional valve (DREBE 6X-1X/175MG24K31A1M) through a PWM signal.
Can you suggest me the hardware and the programming required to do so?
Here's the catalogue, page 92

Hello gtsolid
Keep it simple and stupid firstly.
Follow the example code that comes with the library or
run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.
Have a nice day and enjoy coding in C++.
Thanks for the data sheet link 
The valve is current controlled, not by PWM. You need at least a current generator (DAC...) to control the valve.

Yes agree it’s 4-20mA input , so unsuitable for PWM control ( it maybe loop powered too, I didn’t read that far !)
Yes, you can control it with PWM.
You can generate a 0 to 5V signal using PWM and a filter, then amplify that signal to 0-10V with an opamp.
That's of no use with a current controlled valve.
The choice of the valve control mostly depends on the environment: easy control by PWM or voltage, or interference proof control by current.
The data sheet says 0-10V
