Water meter manual-automatic actuator has two modes:
Automatic mode: Under normal conditions, the actuator can electrically drive the valve to open or close, enabling intelligent and unmanned operation.
Manual mode: In case of power outages, line faults, or other emergencies, you can directly perform emergency operations through the manual knob on the actuator to open or close the valve—no special tools required.
This design of water meter manual-automatic actuator provides the ultimate reliability guarantee. It ensures that critical water supply operations will not be interrupted under extreme conditions, building a solid final line of defense for water supply safety, and serves as an indispensable function in emergency rescue and maintenance work.

Q: How to switch between automatic mode and manual mode of the KY-40 actuator?
A: The actuator switches modes automatically according to the working condition. Under normal power supply and normal line conditions, it works in automatic mode; when power is cut off, line fails or other emergencies occur, you can directly use the manual knob on the actuator to switch to manual mode for operation, without additional switching steps.
Q: Do I need special tools to operate the manual mode of the actuator?
A: No special tools are required. The manual mode is operated through the manual knob on the actuator, which can be directly rotated to open or close the valve, making emergency operation simple and fast.
Q: Can the fully open and fully closed positions of the actuator be adjusted according to actual needs?
A: Yes. The fully open and fully closed positions of the KY-40 actuator can be customized according to customer requirements, which can better adapt to different water supply pipeline scenarios and use needs.
Q: What is the meaning of "Protection: 0" in the product parameters?
A: "Protection: 0" indicates that the product does not have additional special protection functions (such as overcurrent protection, overvoltage protection) in addition to its basic structural protection, and it is recommended to use it under the specified operating voltage range (2.5-5V) to ensure stable operation.
Q: What is the applicable scenario of the KY-40 actuator with a reduction rate of 3500:1?
A: The reduction rate of 3500:1 ensures that the actuator has sufficient output torque (≥2.5Nm) to stably control the valve, which is suitable for medium-sized water supply pipelines that require reliable valve control, and can match the smart water system to realize automatic and manual dual control.
