I want to create an automated irrigation system. So i planned to use the 
Hunter PGV 1" (24VAC) and control the valves with a arduino. First I 
thought this would be easy to use a relays, SRR or triac to control the 
24V AC and turn the power to the valves completely on or off. But then 
saw 2 different currents in the datasheet (370 mA inrush, 210 mA 
holding, 50 HZ). So my question is how do I set this 2 currents? Can I 
use a normal transformer with enough current and the solenoid valve take 
just this ideal current or would I just smoke these valves?

I added my amateur paint schematic of my idea, hope you can help me out.
Btw. I want to control 2 seperate valves.

pls google inrush current and holding current by yourself.

A good power supply like mean well have a current limiter. A bad one can 
be destroyed by current spikes.
