Automatic water meter actuator operates on the principle of hydraulic automatic control, using the pressure difference between the inlet and outlet of the valve as the driving force. Specifically, the electric actuator controls the pressure in the water chamber above the diaphragm, thereby actuating the valve core linkage mechanism to open or close the valve. This approach solves the long-standing problems of control valves in the smart water meter industry, broadening the application environment of smart water meters and extending their service life.

Q: How flexible is the wiring sequence customization? Can it match our existing water meter control board?
A: Customization covers full flexibility: wire color, function definition (e.g., swapping "open/close" signal wires), and wire length. Simply provide your control board’s pin layout (e.g., which pin corresponds to "valve open"), and we will produce the actuator with pre-matched wiring—no on-site modification is needed.
Q: The waterproof grade is IP67—can it withstand long-term exposure to water droplets (e.g., outdoor meter boxes in rainy areas)?
A: IP67 is designed to resist temporary immersion and splashing. For long-term outdoor use with frequent rain, we recommend upgrading to IP68 (permanent submersion resistance up to 1m). The IP68 version adds a secondary sealed housing, ensuring no water ingress even in continuous wet conditions.
