Hello and sorry for this message in english but I am french...
I have a CVA 2660 coffee machine and when I make a coffee a lot of water also flows from the steam valve although it is closed.

It is still possible to make a coffee but this leak reduces the pressure in the expresso brew unit and coffee is not as good as expected and also shorter than expected.

You can see a video there : https://photos.app.goo.gl/ALaUI9XkuCK4tECb2

I was thinking in an issue in the ceramic valve that should close all water paths to steam valve and decompression vessel but not totally sure.

If someone can help me !

Guess you're right, most suspicious part is the ceramic valve. Get a service manual for CVA 2660, if you can't, contact me via "unterhaltungen".

Do you know if the valve can be repaired or the only way is to replace it ?
