I think the first question is do you have a problem with the boiler condensing? If yes, what is causing it?
Fin tube convectors are designed to be used with higher temp. (non condensing) water. If the boiler had condensation issues since installation it's likely that the boiler would have already been replaced by now. If the condensing has just started, you really need to figure out what is causing it.
Even in high temp applications like fin tube, the boiler may still condense a bit when warming up but it should be minimal and go away very shortly.
If you're still in the market for a boiler protection valve you could look at our 280 series valve that is designed for just this. It can be used in a single pump system but you have to remember that it will add pressure drop which could cause flow problems in your system. At that point, a primary/secondary set up may be necessary.
