Not OP but I use motorized ball valves from Amazon [1] which are hooked up to a four way water hose manifold to create four different zones. It's wired up to an ESP32 that controls them with relays via GPIO, using the ESPHome sprinkler controller module (which does pretty much everything OP's code does). I've never had a problem with them and the last time I even touched them was over a year ago. They're pricey but you can DIY them.
The usual sprinkler valves at hardware stores need quite a bit of water pressure to change state which is probably what most people have a problem with, especially if they're trying to feed them with the kind of pumps they get at hydroponic stores.
