We were discussing this problem at the shop earlier today, and a few
interesting observations emerged...

First of all, the valves which are supplied with the tubes that came with
the kit were probably produced the same place that the tubes were, in
China... 'nuff said.   If corrosion with these valves is a problem there
are some alternatives, though, that may be worthy of consideration.  If you
live near a rural community where there's a farm implement store, check
there for the valve stems that they use in tractor tires.  They fill those
tractor tires with calcium chloride and use a special valve stem so they
don't leak... probably stainless steel with special o-rings, like Viton or
somesuch.  Another alternative is the valve stem that they use in your
vehicle's air conditioning system.  Considering the hostile environment
they survive in (for years and years, usually,) they probably would also
qualify as a viable alternative. 

Just some random thoughts on the subject.
