Hello Max, thank you for your question.
The suffix at the end of the Webasto part number changing from A to B or any other letter is the result of a Webasto factory supersession typically following a change to the product or packaging. There is no difference in fit or function and a 9020710B solenoid valve can be used without issue if replacing a 9020710A version.
I hope this is helpful.
Kind regards,
Matt
