And they offer the most wiring options. Seems like CR02 would be best - no permanently energized wire like CR03, just a simple switch. The downside is they don't indicate whether the 3-6v,12v,24v is AC or DC...

They do both AC and DC by the looks of it.

Wiring diagram CR02 is for DC definitely.

I think CRO3 is for AC controllers as the supply options are 3-6, 12/24 and 220V (220V is mains AC in many parts of the world). The supply is labeled as "IS" rather than +ve and -ve, which are DC only supply terminal labels.

CR04 is also for AC but without an earthing lead which to me says that would be the one for low voltage AC supply.

Seeing that 1/2'' copper pipe for plumbing has a typical OD of 5/8'', I guess the correct valve would be the 3/4'' valve. You would then thread the pipe and use teflon tape to seal the join.

Thanks for link! I had to buy 50 in order to get them for $17.50, then there was bank fees, and heavy shipping. Might use this in the future as I think these are coming from the same place.

50 for a single setup or planning to sell them on the flip?

I sold them awhile back, in order to get my overall costs down. Sold through them quick and keeping my 2 extra just in case.

Good links. I had no idea you could get motorized SS valves for those kind of prices. Although I would prefer EPDM over Viton seals, personally, for hot stuff.

These things are only rated for 176 deg and 194 deg F? Am I missing something?

The alternatives are also rated at this temperature.

Yes, they won't be suitable for boiling wort however, when do you actually transfer boiling wort? The hottest part of your system will be the outlet of the brew kettle. the valve will be open after you whirlpool the wort and are transferring it to the heat exchanger.

You probably whirlpooled for around 5 mins and let it stand for another 5 mins. anyway, my point is that the wort is not at 212 when it comes out of the kettle. It's probably dropped by a good 15 degrees during this time.

That's still right on the upper edge of these valve's operating parameters but much better than a boiling transfer operation.
