    Decent 18 gauge stranded copper or low capacitance alloy ( Trane Purple ). Shield is not necessary if these are binary ( on / off ) but if they are proportional ( analog ) it might be worth the little extra.

    You would be safe running 4 conductors per valve.
    Assuming all the end switches will be tied together, the bare minimum would be 2 per valve and 2 for all the end switches.
