Todd,
You’re probably correct on the
costs, but are you sure these are strictly on/off devices? Looking at the
url doc Paul referenced, it appears these are infinitely variable valves.
If this is the case, it would be more desirable (to me) and worth a few extra
ounces (and $).

valve
An electrically operated solenoid valve is
reasonably inexpensive and not too heavy, but is strictly an on/off valve. An
electrically actuated control valve is very $$$$, bulky and heavy. Unless if
you know of a source for one that is none of these. I think this is a case
where we are about to try to over-engineer a simple device. Better to leave
this one to ACRE.

Todd,
What about the electrically operated
valves (see list from Paul). It looks like it would be easier to install
in that you don’t have any control cable running through the
firewall. And you won’t have the cable sticking out into the cabin,
just a switch.
