Not familiar with that make but any basic flow control valve should do, mine are similar to these and rated at the same 10bar does not mean you have to put that much into them. You can get inline ones too.
Watch this video I posted yesterday, after 60 seconds all speed is being controlled by one of those valves, towards the end you can see that I have set the compressor regulator to approx 10psi so the valve and the engine only sees that.
