Solenoid Valves are used to control access and flow for each individual zone of an automated irrigation system. The wires, either DC or AC, connect to multicore cable, which in turn, connects to the automatic controller programmed to open and close these valves based on watering requirements. DC valves are usually used with battery operated or low voltage controllers, and are identifiable by the red/black wire combination. AC valves are for standard 240V controllers with red/red wire combo. Dural Irrigation is your trusted online supplier for solenoid valves.
