Nest thermostat controlling 24 V valves for baseboard water heat

I am installing Nest thermostats to control 24 V valves (normally closed) for baseboard water heat. These will keep those rooms cool when they are not needed.

I know I should connect the 24 V transformer to the Rc and C terminals. How to I power the 24 V valves?

How are you powering the valves currently?

Welcome to the the forums,

The nest doesn't supply 24v to the valves.
It switches it from a transformer you should have already in place.
A few pictures of your wiring around the valves would be helpful..... how-to-insert-pictures.
