What is the term for this valve I'd like to control?
I'm working on making my own 'smart' sprinkler system, something internet connected that I can control with my phone while I'm at work. I bought an Orbit brand electronic sprinkler timer and took it apart to learn about it and use parts. The valve inside seems to be controlled with a 24v pulse and then switches from closed to open and vice versa. I'm somewhat familiar with something like a normally closed or normally open solenoid where voltage is constantly applied to change states but I'm not sure what this valve is called to do more research. I need to do more research because although I can get it to switch states sometimes with three 9v batteries in series I can't get it to switch reliably. TIA!

It's a "solenoid valve", or irrigation solenoid valve.
9V batteries can't supply much current, thus probably not suited to drive a solenoid valve. You need a stiffer power source. If you have a ammeter, measure the current at the rated voltage and choose a suitable power source.

Are you sure you are seeing a valve inside the timer? I have never seen a sprinkler timer with that sort of arrangement. Since most sprinkler systems have multiple zones they have multiple valves controlling each zone.
You can get manuals for Orbit timers online. I would suggest you look on line for the manuals that match your timer.

I can't identify the valve used in your
Orbit sprinkler control without a model
In all cases solenoid valves are used.
Solenoid valves are self closing under
water pressure and require power only
while open. The power required is beyond
seriesed 9V batteries.
I can't guess what kind of modem you use to relay power from your phone code.
Hopefully, it can relay 24VDC from a
