The 2-Strand Direct Burial Wire (1 Valve) is the essential wiring solution for connecting a single irrigation valve to an AC electronic irrigation timer or controller. One strand carries the signal from the controller to the valve solenoid, while the second strand serves as the common (return) wire — the two connections every single-zone wired valve requires.
Rated for direct burial, this wire can be run through soil with or without conduit, making installation clean and straightforward. Available in 100', 250', and 500' lengths to match your project size. Use waterproof wire connectors at all splice points to protect connections from moisture and corrosion underground.

What is the second wire (common) used for?
The common wire is the shared return path that completes the electrical circuit between your controller and the valve solenoid. One wire carries the signal to open the valve; the common wire returns the current back to the controller.
Can I bury this wire directly in the ground?
Yes — this wire is rated for direct burial and can be run through soil with or without conduit.
Running it through conduit adds extra protection and makes future repairs easier, but it is not required.
Will this wire work with DC battery-operated valves?
This wire is intended for use with AC electronic controllers and valves. DC battery-operated valves use a different voltage and are typically wired differently — verify your valve and controller type before purchasing.
What do I need to protect the wire connections underground?
Use waterproof wire connectors at every splice point to seal out moisture and prevent corrosion, which can cause valve failures over time.
