Wiring Zone Pumps with Zone Valves

Hey guys! So I have a job coming up that’s got 4 zone pumps as well as zone valves. Since this one is kinda new to me, I’m wondering if I can get some help with wiring as my first thought is to just use a zone switching relay AND a zone controller- but something tells me there’s an easier way. I just don’t see the zone controller having the capability to run the 4 pumps and I don’t see 24v spots on the Zone switching relay 🤷🏻‍♂️

    Does the design have a zone circ and a zone valve on each zone? The cleanest way to control that would be to install a zone valve controller to manage the t-stats and zone valves then install a switching relay for the circs. You could tie the zone valve end switches to the t-stat terminals on the switching relay so the circ will not fire until the valve is fully open.
    Now I must ask why. A properly piped zone circ system with flow checks does not need zone valves. If you are concerned about ghosting on the side with no flow check, you could pipe a heat trap. Zone circs with zone valves add cost, unnecessary complication, and more failure points IMO.

    Is this 8 zones or are you using the zone valves as flow checks?
