The far corners of a farm are exactly where wired control stops making sense. The 4G Smart Irrigation Valve solves this by building the cellular modem into the actuator itself: each unit accepts open, close and schedule commands straight over the mobile network, reports its position back, and needs no gateway, no trenching and no cable between fields. Kaiye Electric builds the KY-KT-35 platform as the manufacturer, so wiring order, labeling and platform protocol are decided on the production line, not retrofitted by an integrator.
Where the previous generation of actuators waited for a field gateway to relay instructions, this unit dials the irrigation platform on its own. That single change removes the most expensive and most fragile part of a large installation.
For scattered plots, rented land and roadside valve points, a 4G Smart Irrigation Valve is the shortest path from a map pin to working automation.
Torque is the number that decides whether an actuator survives its second season of grit, scale and a stem that has not moved since last autumn.
Every unit is run against these figures before shipment, which is why the 4G Smart Irrigation Valve can be specified for buried-chamber and above-ground installations alike.

| Valve sizes | DN80–DN100 |
| Ingress protection | IP65 |
| Battery life | Over 5 years (typical duty) |
| Manual override | Yes, on-body |
Custom torque ranges, cable lengths and battery capacities are quoted against your valve schedule, so the specification you receive is the specification that ships.
Five cores leave the actuator, and their order is decided with you rather than for you — a small point that saves hours of rework during commissioning.
| Core | Color | Function |
|---|---|---|
| I | Blue | Open / close signal |
| II | White | COM |
| III | Yellow | Open / close signal |
| IV | Red | Positive |
| V | Black | Negative |
The line sequence is customizable at order time. Two optional position-sensing kits extend the standard open/close feedback: a photoelectric reflection PCB that counts pulses for multi-angle positioning, and a magnet variant that reports angle magnetically for sealed chambers.
With wiring agreed up front and feedback kits matched to the chamber type, the 4G Smart Irrigation Valve installs in a single site visit.
Cellular control pays for itself wherever the valve sits far from both power and people.
If your site map shows more than a few valves per hectare inside one contiguous block, ask us to compare this unit against the gateway-based sibling model before you order, since a 4G Smart Irrigation Valve is priced for independence rather than density.
Most orders ship with the customer's own wiring order, logo and platform handshake already in place, because retrofitting these after delivery is the slow way round.
Send the valve schedule and site conditions, and the 4G Smart Irrigation Valve configuration — torque, battery, feedback kit, wiring — is confirmed in writing before a price is issued.
A Yes — each unit holds its own cellular subscription, which is precisely what removes the gateway, its power supply and its commissioning from the bill of materials. Data consumption is modest because the actuator reports position and status rather than streaming data, but for dense blocks of valves per hectare we will also quote the gateway-based sibling model so you can compare both running costs before committing.
A Schedules stored on the actuator keep running locally, so watering is not interrupted by a coverage gap. Status updates queue and resume when the network returns, and the manual override keeps the point operable in the meantime. Before ordering, we recommend a simple signal survey at each chamber location; for sites that are permanently shielded, the LoRa gateway model is the better fit.
A The standard unit provides full open/close travel with closed-loop limit feedback. For intermediate positions, two optional kits are available: a photoelectric reflection PCB that positions by counting pulses, and a magnet-based variant suited to sealed chambers. Specify which one you need at order time, since the sensing PCB is fitted during assembly.
A A 3.6 V lithium pack powers the unit, with the electronics accepting a working window of 2.5–5 V and drawing no more than 100 mA unloaded. Between scheduled operations the actuator sleeps, which is how the datasheet supports over five years of field service under typical daily switching. Higher switching frequencies are factored into the battery sizing at quotation.
A Yes. Third-party platform integration is a standard part of the offer: we supply protocol documentation and work with your integrator during the handshake phase. OEM customers regularly run these units on their own cloud platforms, and the same unit hardware is reused across projects so firmware behavior stays predictable.
