Hunter Wireless Valve Link: Add valves where wire can't go
12 Jun 2026, 10:22:17
Hunter's Wireless Valve Link replaces field cabling with a license-free radio link, so you can add up to 54 valves to an existing ICC2, HCC, or MCC controller without trenching, boring, or breaking up hardscape.
Why the Wireless Valve Link exists
Every installer knows the situation: a project that would be straightforward except for one stretch of asphalt, one ornamental lawn, or one neighbour's driveway that nobody wants to dig up. Conventional irrigation depends on copper running from the controller to every valve, and the cost and disruption of laying that wire often decides whether a project is viable at all. Cable also stays vulnerable for the life of the system — to mowers, aerators, renovation work, root growth, and lightning surge.
The Hunter Wireless Valve Link removes the wire from the equation. Each valve box gets a small battery- or solar-powered radio unit that talks directly to a module inside the controller, over distances of up to roughly 600 metres line-of-sight, and further again with a repeater. No new trenches, no hardscape cuts, and no field cable to fail later.
The short version
The Wireless Valve Link is the right choice when running cable to a new or replacement valve would cost more than the irrigation it controls — across roads, around buildings, into mature gardens, or out to remote zones on sports and golf sites.
How it works in the field
The system is built around two devices. A Wireless Valve Output Module (WVOM) slots into a Hunter ICC2, HCC, or MCC controller in place of a conventional station module. Out in the field, one or more Wireless Valve Link units sit inside the valve box and operate the solenoids directly. Communication runs over a license-free LoRa radio link, with two-way confirmation so the controller knows the command was received and the valve actually opened.
WVL units come in single-station, two-station, and four-station versions, so a typical valve box can be served by one unit. Each WVL connects to the solenoid by a short length of low-voltage wire (up to 30 metres with 18 AWG cable), which means the valve itself doesn't need to sit directly under the radio. Setup is done from a free Bluetooth app on iOS or Android, including a built-in site survey to confirm signal quality before you commission.
Where line-of-sight is broken by buildings, dense planting, or terrain, a solar-powered repeater (RPT) extends coverage and can roughly double the working range. An antenna extension kit is also available where the controller is in a basement, metal cabinet, or other location that weakens the signal.
Where it makes the biggest difference
Five situations come up again and again in projects we see across our markets:
- Commercial sites with hardscape - parking lots, shopping centres, business parks where greenery sits behind concrete and tarmac
- Public spaces - roundabouts, central medians, parks with paths or water features in the way
- Sports fields and golf courses - adding practice areas or new zones to an existing controller without trenching across the main playing surface
- Mature gardens and heritage sites - adding irrigation without tearing up established lawns, paving, or protected root systems
- High-lightning areas - because there's no copper wire between the valve box and the controller, a strike at the valve can't travel back down a wire and take out the controller
Frequently Asked Questions (FAQ)
Does the WVL replace the controller?
No. It works alongside Hunter's ICC2, HCC, and MCC controllers. A WVOM is added to the controller and acts as the radio bridge to the WVL units in the field.
Can I mix wireless and wired valves on the same controller?
Yes. The WVL can be combined with conventional ICM modules or two-wire EZDS modules in the same controller, up to a total of 54 stations plus pump/master valve.
What range can I realistically expect?
Up to roughly 600 metres line-of-sight under ideal conditions, and further with a repeater. Buildings, dense foliage, and terrain reduce that figure, which is why Hunter includes a site survey function in the WVL app — always run it before final installation.
How is the WVL powered?
Each WVL runs on 9 VDC batteries, with one or two units per WVL depending on configuration. Batteries typically need replacing once a season or once a year. For long-term installations and remote zones, a solar panel kit (SP-WVL) keeps the unit topped up indefinitely.
Is the WVL suitable for lightning-prone sites?
Yes — that's one of its strongest selling points. Because there's no copper wire between the valve box and the controller, a lightning strike on a valve has nothing to travel back along. This isolation protects the controller from surge events that frequently destroy conventional wired systems.
Which solenoids does the WVL work with?
The WVL operates Hunter DC-latching solenoids (part number 458200), which fit all standard Hunter irrigation valves. Existing AC solenoids must be swapped to the DC-latching version when converting a valve to wireless control.
