Thanks for the info. A 120V N.O. valve and the 120V version of the A-419 looks like the ticket. Did you use any thermal grease? Would it be wise to use a rubber stopper, cork with a hole, etc. to hold the probe in place. I remember my dad having something like silly putty but I think it was for electrical purposes. Since I think it was rubber insulation that would work too but I don't know what it was.
