If you are sourcing valve actuators for smart water meters, purification systems, or small-bore pipeline control at volume, the KY-KT-27 is built for one purpose: to close and open valves reliably on command, cycle after cycle, without adding maintenance burden to your product or project.
Kaiye has manufactured water meter actuators since the early adoption of smart metering, with an annual actuator capacity of 10 million sets and over 30 years of hardware and control-valve production experience. The KY-KT-27 is part of that volume-proven platform—engineered for OEM integration, batch consistency, and predictable lead times.
This is not a catalog placeholder. Below you will find the actual working parameters, mounting and wiring logic, procurement limits, and the technical questions your engineering team will ask before approving a sample.
Most smart-meter valve failures do not come from electronics. They come from torque falling short on aged valves, sealing failure in humid meter boxes, or wiring configurations that do not match the meter platform. The KY-KT-27 addresses these three failure points directly.
Rated at ≥1.8 N·m through a 2400:1 metal-gear reduction, the actuator is sized for DN15 and DN20 water-meter valves. Metal gears are machined, not sintered, which preserves torque output over long cycling and reduces the risk of stripped teeth under stall conditions.
Meter boxes are humid, occasionally submerged, and exposed to condensation. The IP66 housing protects the drive train and control electronics, allowing the actuator to remain functional in outdoor pits, utility cabinets, and purification equipment enclosures.
When the optional water-leakage alarm cable detects water contact, the actuator automatically drives the valve closed and activates a red indicator. This is a hard-wired safety response that operates independently of the upstream meter electronics, reducing dependence on firmware intervention.
Installation teams need to operate the valve before power is applied, and maintenance crews need a way to open or close the valve during service. The KY-KT-27 supports manual emergency operation alongside electric remote control, so the valve is never stranded.
The table below reflects the standard KY-KT-27 configuration. Where your meter platform operates on a different voltage, torque curve, or wiring convention, these parameters can be customized during the OEM review.
| Parameter | Standard Value | Procurement Note |
|---|---|---|
| Model | KY-KT-27 | Confirm model code on sample and datasheet |
| Rated Voltage | 24 V DC | Operating range 23–25 V; confirm compatibility with meter power rail |
| Operating Current | ≤80 mA | Budget for peak current during valve travel, not only standby |
| Locked-rotor Current | 450 mA | Useful for driver and protection circuit sizing |
| Output Torque | ≥1.8 N·m | Measured at rated voltage; confirm against valve seating torque |
| Reduction Ratio | 2400:1 | Matched to DN15–DN20 valve platform |
| Valve Response Time | ≤10 s | Open-to-close or close-to-open at rated voltage |
| Waterproof Rating | IP66 | Suitable for humid, splash-prone, and outdoor meter enclosures |
| Wiring | Power cable + leakage alarm cable | Cable length, connector type, and wire color can be customized |
If your application runs on 3.6 V, 5 V, or 12 V, or requires a different torque tier, Kaiye’s engineering team can review the valve load and propose a matched actuator configuration rather than forcing a standard SKU into an incompatible valve platform.
For OEM buyers, the actuator is only as good as its fit with the meter housing, valve stem, and control board. The KY-KT-27 uses a compact, integrated outline intended for space-constrained smart-meter enclosures, with a wiring scheme that separates power from the leakage-detection circuit.
Power wiring. The actuator is powered through a dedicated cable. The drive circuit should be sized for the locked-rotor current of 450 mA, even if normal operating current is ≤80 mA, because valve seating can briefly demand higher current. Reverse-polarity protection on the meter board is recommended if the actuator is field-replaceable.
Leakage alarm wiring. The leakage cable is a separate input. When the sensing cable detects water contact, the actuator closes the valve and triggers the red alarm indicator. This circuit should be treated as a safety input, not a metering signal, and should remain independent of the communication module so that a communication failure does not disable leak-triggered closure.
Mounting interface. The actuator is designed around the valve stem and mounting pattern used on DN15–DN20 smart-meter valve bodies. Before volume release, buyers should confirm stem square, mounting hole spacing, and actuator orientation inside the meter housing. Kaiye can supply a sample for mechanical fit-check before the production order is placed.
If you are also sourcing the meter housing or the complete valve assembly, the actuator can be reviewed together with the water meter shell and valve body to reduce interface mismatch at assembly.
The actuator is positioned for small-bore valve control where electric remote operation and fail-safe closure matter more than high-speed actuation. Typical volume applications include:
Remote open/close for billing control, arrears management, and leak response in apartment buildings and utility-managed residential accounts.
Automatic shut-off on leak detection, tank-level control, and filter-cycle valve operation in point-of-use and commercial purification equipment.
Batch installation in old-community renovation, campus water management, and industrial park sub-metering where actuators are procured in four- or five-digit quantities.
Actuator supply to water-meter manufacturers and valve automation shops that integrate the actuator into their own meter or valve product before shipping to the utility.
Because the actuator is part of Kaiye’s broader water-meter component platform, buyers sourcing multiple components can consolidate qualification and logistics. If your project also requires wireless communication at the meter level, the actuator is designed to work alongside Kaiye’s wireless water meter platform, where valve control and remote data transmission are treated as one system rather than two separately qualified parts.
For B2B buyers, “manufacturer” should mean process control, not just a trading company with a catalog. Kaiye operates an ISO 9001 quality system, runs automated production for actuator assemblies, and has been producing water-meter actuators for more than two decades. The KY-KT-27 benefits from that production base in three concrete ways:
Batch consistency. Metal gears are machined to controlled dimensions. Automated assembly reduces unit-to-unit variation in gear mesh, torque output, and response time—critical when you are installing thousands of actuators across a utility project.
Incoming inspection and final test. Standard production includes functional checks for current draw, response time, and valve travel. Buyers can request the inspection protocol and sampling plan before placing a volume order.
Traceability. Model code, production batch, and test records are retained so that if a field issue appears, the affected population can be isolated rather than treating every actuator in the project as suspect.

The KY-KT-27 is available as a standard unit, but standard does not mean fixed. For OEM and project buyers, the following items are commonly customized after technical review:
Voltage and drive logic. If your meter board supplies 3.6 V, 5 V, or 12 V instead of 24 V, the actuator drive can be reviewed and matched. Control signal polarity and open/close logic can also be aligned with your board.
Cable and connector. Cable length, wire gauge, color code, and connector type can be specified to match your meter housing and assembly fixture.
Torque and gear ratio. For valves with higher seating torque or different stem geometry, an alternative gear ratio or motor tier may be more appropriate than the standard 2400:1 configuration.
Branding and packaging. Private-label marking, neutral packaging, and project-specific labeling are available for volume orders.
Typical MOQ for standard configuration starts at 500 pieces; customized voltage, cable, or branding may require a higher MOQ and a sample approval step. Lead time for standard units is generally 15–25 working days after PO and sample confirmation, depending on order quantity and component availability. Final MOQ and lead time are confirmed at quotation.
