Orbit Underground Sprinkler Wire 7-Strand 50 ft, 18‑Gauge — Direct‑Burial, UV‑Resistant PVC Jacket

Orbit Underground Sprinkler Wire 7-strand, 50 ft, 18-gauge is a direct-burial valve control cable designed to deliver dependable 24 VAC signals from your controller to multiple irrigation valves.

This professional-quality valve wire combines seven individually insulated copper conductors with a tough, UV-resistant PVC jacket so you can bury it without conduit and expect long-lasting performance in yard and landscape systems. It supports common irrigation controllers and valve brands, simplifies zone wiring with color-coded insulation, and is sized to carry the typical 24 VAC solenoid current out to several hundred feet.

How far can this wire reliably carry a valve signal?

The 18-gauge copper conductors in this wire are specified to transmit 24 VAC control signals effectively up to the manufacturer-recommended distance for typical solenoids. For most single-valve runs you can expect stable operation well within the stated range.

• Maximum recommended length for one solenoid: up to 800 feet
• 18 AWG copper minimizes voltage drop compared with thinner conductors
• Seven conductors allow control of up to six zones plus one common

Will this wire stand up to direct burial and outdoor conditions?

The cable is designed specifically for underground use: each conductor is insulated and the outer jacket is a heavy-duty, UV-resistant PVC that resists moisture and freeze/thaw cycles. That means you can bury it in typical landscaping soils without additional protective conduit for most residential and commercial installs.

• UV-resistant PVC jacket reduces degradation from sunlight where exposed
• Water-resistant construction helps prevent shorting and corrosion
• Meant for direct burial in lawns, beds, and utility trenches

Is this wire compatible with my existing sprinkler system?

Yes — the wire is manufactured to industry standards so it pairs with common irrigation controllers and valves from major brands. The color-coded insulation on each conductor speeds up hookup and troubleshooting during installation.

• Works with Orbit, Hydro-Rain, Rain Bird, Hunter, and other controllers/valves
• Color-coded conductors simplify matching to zone terminals and commons
• Standard 24 VAC signal support for typical irrigation solenoids

How should I plan wiring for a multi-zone system with this cable?

Use the seven conductors to run multiple valve circuits plus a single common return conductor back to the controller. For larger systems you can run multiple cables or combine with conduit-fed spurs to keep voltage drop and wire runs organized.

• One conductor per zone, one conductor used as the common/shared return
• For long runs or high-current solenoids, plan gauge and routing to limit voltage drop
• Splice and waterproof connections with irrigation-rated connectors or heat-shrink kits

Who this is for: Landscapers, irrigation installers, and homeowners upgrading or building sprinkler systems who need a robust, 7-conductor direct-burial cable for controlling multiple valves. It’s especially suited to projects requiring color-coded wiring, compatibility with common controllers, and runs where burying cable without conduit is preferred.
