I would like to fit a full bore quarter turn valve that takes 25mm MDPE on the inlet and 22mm copper on the other side. I can't seem to find one, but surely they exist - has anyone come across one?

I need to replace a seized stopcock on a 25mm blue MDPE supply pipe to 22mm copper internal pipework and my preference would be for a full bore lever valve that's a direct fit to both pipes (less prone to seizing I hope).

If such a thing doesn't exist, then I'll use a converter on one of the pipes but I want to consult with those better informed than myself first.
 
I was hoping for a 1/4 turn ball valve type, both for ease of use and to minimise restriction of the flow (which is perhaps negligible). Thanks for the suggestion though - may end up going that way.
