Manufactured by Cixi Kaiye Electric CO., LTD
The waterproof DC meter gear motor is a high-performance miniature DC gear motor, purpose-built as the core driving actuator for smart water metering systems. With an optimized gear structure and IP66 ingress protection, it delivers reliable low-power operation, fast valve actuation and stable performance in humid, water-exposed working environments.
• Residential valve-controlled smart water meters
• Small-caliber remote automatic meter reading (AMR) systems
• DN15–DN20 water meter motorized valves
• Miniature fluid control valve drives
All parameters are tested under standard ambient temperature (23 °C) at rated 3.6 V DC operating voltage, unless otherwise specified.
| Parameter Item | Standard Value & Notes |
| Rated Operating Voltage | 3.6 V DC |
| Allowable Operating Voltage Range | 2.5 V – 5 V DCNote: Higher input voltage within this range delivers higher output torque, but will reduce the service life of the unit. |

Note: Wire sequence, color coding, wire length and wire gauge can be fully customized according to customer’s specific requirements.
Q: What pipe and valve sizes is the KY-30 compatible with?
A: Optimized with a 2000:1 gear reduction ratio and ≥1.5 N·m output torque, the KY-30 is perfectly matched with DN15 and DN20 residential smart water meters, as well as other small-caliber motorized fluid control valves.
Q: What actual protection does the IP66 rating provide?
A: IP66 rating means the unit is fully dust-tight and resistant to high-pressure water jets from any direction. It is designed for long-term stable operation in the humid, water-exposed working environment of smart water meters, effectively preventing dust and water ingress from damaging internal components.
Q: Can the wire sequence and wire specifications be customized?
A: Yes. We support full customization of wire sequence, color coding, wire length, wire gauge and connector type to fully match your specific assembly, installation and control system requirements.
1.
Q: What power supply is recommended for the KY-30?
A: The rated operating voltage is 3.6 V DC, with an allowable working range of 2.5 V to 5 V DC. We recommend a stable 3.6 V lithium battery power supply to balance output performance, low power consumption and long service life.
Q: Is this motor compatible with mainstream smart water meter control systems?
A: Yes. The waterproof DC meter gear motor adopts a universal micro-power design and standard in-position signal output, which is highly compatible with most mainstream smart water meter control boards and remote meter reading (AMR) systems.
