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???

This may sound familiar.

Post your schematic.

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

Because I answered an electronics question with a plumbing answer? Or was it the nomenclature that I used?

I was thinking in medical terms.

Ok, this isn't the sixth grade, if your going to giggle about that, try and keep it to yourself.

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???

Take a photo of your entire circuit, both sides of the PCB.
