Smart irrigation
Smart Valve Node
A solar, wireless valve controller shaped like the hand-wheel it replaces.
The challenge
Opening and closing valves by hand across a large site takes hours of walking every day.
Smart Valve Node
Misting, irrigation and water features are spread across enclosures and landscapes, and every change means a trip to the valve. The Smart Valve Node runs up to four valves from one solar-powered unit, takes its orders from the site controller over LoRaWAN and still works by hand with a magnet key.
Water & Aquatic
Where it works
Enclosure misting & irrigation
Humidity and watering for animal enclosures, on schedule or on demand.
Landscape & lawn zones
Zones across a large campus run from one place instead of by hand.
Polyhouses & nurseries
Watering for plant houses and nursery beds, set and checked remotely.
What it does
Up to four valves
Opens and closes latching DC solenoid valves on command from the site controller.
Hand override
Hold the magnet key on OPEN or CLOSE, even if the controller is down.
Fails safe
Closes its valves if it loses contact with the controller, and again after a restart.
Never strands a valve open
It will not open a valve unless the battery can close it again.
Flow & leak watch
Counts flow while valves are open and flags flow when they are all closed.
Keeps valves healthy
Checks each valve coil and exercises idle valves so they do not seize.
How it works
Fit
Mount the node on a pole beside the valve chamber, or inside it, and connect up to four valves.
Link
It joins the site controller over LoRaWAN, powered by its own solar panel.
Run
Valves open and close on schedule or on command, or by hand with the magnet key.
Why teams choose it
Less walking
Change valves across the site without visiting each one.
No power cable
Solar panel and battery: it goes wherever the valve is.
Safe by hand
The magnet key gives authorised staff a manual override.
Catches leaks
Flow readings show a burst pipe or a valve that did not close.
