I need to get the correct 24v transformer that can handle the load.
I have 8 zone valves that are rated at 0.32 amps each.
I think the formula is:
24v * 0.32Amp = 7.68VA
...but I am not sure. That seems a bit too simple.
If it is correct, then I would need a transformer rated no less than 61.44VA, thus buying a 70VA will do.

Definitely, not WATTS. I need to make sure that the working load (amps) doesn't blow the transformer or any inline fuses that I install.

One more thing. I do have two 50VA transformers (old, but still new in the boxes). I can surely split the load and run 4 zones on one, and the 4 other zones on the other. By the way, I "am" the professional. Hehehe. This is not for my house, but more as a favor for somebody else's house.
I just needed a quick "weekend answer", since the warehouses and tech support are not open on Sundays.

No, you have it right. 8*.32 = 2.56A (if they're all turned on at the same time) so, at 24 volts, that's
24*2.56 = 61.44VA.

Go to home depot or something.What is this for?
Really ..Have you interest in the "battery industry"..lol
No really you want a "math equation "But what you really
need is a new transformer,maybe your home needs re wiring.
Yes I think buying 70va will do.if considering your load
can handle the output.of atleast 8 extra.If it can't then you
need to get the correct transformer period.My advice is
contact a electrician or an qualified contracter experienced
in the "reality" of such matters.If you don't know ,but the
mathmatical equation or aspects.is all you do?You seriously
need to rethink of the importance of the transformer and
it's purpose .You wouldn't want to blow out anything or cause a fire.Ouch..

I think you are adding apples and carrots.
If you are using 8 valves which each draw .32 amps. Then 8 times .32 amps. = 2.56 amps.
You need a 24volt transformer that puts out 2.56 amps or higher.
volts times amps with DC current =voltamps=watts.
volts times amps with AC current =voltamps and voltamps +a power factor = watts
you cannot change voltamps to amps.

"If it is correct, then I would need a transformer rated no less than 61.44VA, thus buying a 70VA will do."
On electronics components you are MUCH safer going with a 2X margin than a 15% margin of tolerance. A little overheating or power surge and you may cook that puppy.

don't you have to divide your answer 7.68 by 1000
