What is the difference between 9 V and 24 V solenoid valves?
24 V AC (alternating current) for fixed/smart controllers, 9 V (solenoid valve) for battery-powered controllers.
Solenoid valves open and close the individual irrigation circuits. They are available in 24 V AC (alternating current) and 9 V (solenoid valve).
Use 24 V when you have a fixed or smart controller connected to the mains (e.g. Hunter X-Core or Hunter HPC).
You need 9 V if you use a battery-powered controller – there are also battery-powered controllers with App/Bluetooth/WLAN.
Important: The voltage of the controller must match the voltage of the valves.
In short: Power available → 24 V valves. No power → 9 V valves.
