Pump and master valve connections will typically output 24VAC when any zone is on. Some solenoid valves work that way, some don't.

A few controllers can output multiple master valve outputs depending on which zone(s) are activated.

One warning: Some solenoid valves open/close almost instantaneously which can put a large shockload on your piping. Slower valves are available, here's a random one example (not a recommendation) I found on Amazon: https://www.amazon.com/Motorized-Function-Standard-U-S-Solid/dp/B083XH811X/.
