Question Arduino and MOSFET IRL540

Good day, all
I have the Arduino UNO and try to activate a valve, therefore I have the IRL540 MOSFET. On Gate we have the 0 or 5V signal from the arduino to switch (on/off), on drain we have 12V for the powersupply. But if we give the 5V on gate we only get 2,7V on the Source what is not enought to switch the valve.

Is there anyone have ideas o it? Thank you in advance!

Ground source, output from 12V and drain.
