I'm using MCU turn on a relay,then relay turn on solenoid valve.But when valve on 1 times,all things stuck at there.If i remove the valve,and left behind the 240V,everythings work fine.Is than i need to choose a low voltage valve???

Check the plumbing configuration. If you put the 'in' on the 'out' it can get stuck open.

brother blueroom,i can say that my circuit no have any problems,because i remove the valve,and test the 240v life cable,it will turn on and off follow by the relay. I can sure that the problems cum from the valve.

The valve have 2 pins,and it got polarity???
