This is the second one that I purchased for two projects

I purchased one for a Google nest thermostat and the second for a video doorbell. They worked perfectly on both.

I'm assuming that the pictured xformer is the one you want to use as a replacement. It looks like that model can be used with a plate mount or stand alone so as long as the winding ratio, voltage and volt-amp (VA) ratings match it should work fine. That's a 5:1 (120Vac to 24Vac) step down control xformer if memory serves. I found the average output on that model to be 27Vac.

Q: Can I use this transformer with v8043 E 1004? If so, how many zone valves can I connect to the transformer? I'm installing an 10 zone system expandable to 12 zones.

You can use more than one transformer per zone valve but I only use one because it will get overloaded if one valve starts binding up.

A quick search shows each valve is 7.7 VA, wants to connect minimum 10. However transformer is 40VA, so if all acted at once there would be problems

Q: will this transformer be adequate for both a v8043e1012 and a v8043f1051 valve simaltaneously

Asked by Sal 13 years ago

Each valve draws .3 amps. A 40va transformer can handle 1.6 amps at 24 volts. So your total of .6 amps is well within the limits of the transformer.

It may be OK, but do yourself a favor and use two power supplies so if there is a problem you know exactly where it is.
