There are a lot of ideas in this discussion: http://www.element14.com/community/thread/25296
The first page of comments assumed that the device being controlled was 24V DC, but by the second page it seems that it's a 24V AC valve like yours. So a relay, triac, or opto-isolated triac are good possibilities.
