Any reason for not going with 220/110V instead of 24/12V on these valves?

12/24VDC can be controlled by a transistor. 110/220VAC must use a relay or triac.

Okay. But for the use with for example Brewtroller where it's wired with power always on and a control line switched to +12V or live to open, wouldn't it be the same?

For example the following valve with BD3 wiring:

Those wiring diagrams just show a generic switch. Transistor, relay, triac, SSR are just different types of switch. They all work, but a transistor is probably cheapest and easiest to interface with a microcontroller. If you already have an external relay board it will probably work with both 24VDC and 240VAC so it hardly matters.

I went rigth to KLD that distributes to OSCSYS. I spend a little under $300 for (3) 3way and (1) 2way valves shipped. Just got them a while ago and they work great.
Plus the customer service was really nice. Although, the time zone differance made communication difficult.

Id recommend them.

My understanding is OSCSYS no longer buys from KLD, doesn't seem to be too many details as to why....
