Hello,
Being about to play with solenoid valve, I've ever found several information on this previous topic
I'm fairly new to electronic stuff, but read something about MOSFET transistor. Does this prevent from current feedback? replacing a diode?
Thanks for your experience
Not sure what it is you are trying to ask.
Try starting out by stating your objective.
Being about to play with solenoid valve
is really rather vague.
What do you want to do with it ?
"My objective is _________________________________.
Then state your progress as it currently stands:
"My current progress is :
I have been able to :_______________________
but am having problems with ______________________"
Post a schematic of your objective or circuit .
"Attached is my schematic.."

Caution: There's a hidden link at the end of OP's post, visible when I took it as a quote....
But anyway, to answer the question, which doesn't actually rely on knowing what it means to play with a solenoid valve, no a mosfet (a mosfet transistor would be a mosfett 
like a pin number....) does not prevent the current feedback, you still need a diode to do that. The mosfet switches the power to the solenoid from the external power supply that you will need, since you can't power the solenoid from the Arduino; you can only control it.
The below is a good diagram of how to hook it up; just pretend the "M" for motor is your solenoid.
Useful schematic.

Feel free to discuss solenoids and Arduinos. Don't expect a response from nutnkss.
