This Low Noise Water Meter Gear Motor is purpose-built for smart water metering systems, with core application scenarios including:
• Wireless residential smart water meters
• Prepaid valve-controlled smart water meters
• Remote automatic meter reading (AMR) systems
• Motorized valves for DN15–DN50 water metering pipelines
Unless otherwise specified, all parameters for the Low Noise Water Meter Gear Motor used in water meters are tested at a standard ambient temperature (23°C) and rated operating voltage.
1. Rated operating voltage: 3.6 V DC
2. Allowable operating voltage range: 2.5 V – 5 V DCNote: Within the allowable range, higher input voltage delivers higher output torque, but will reduce the service life of the actuator.
3. No-load operating current at rated voltage: ≤ 25 mA
4. Locked-rotor (stall) current at rated voltage: ≤ 450 mA (for 300-series motor)
5. Rated output torque:
o ≥ 1.8 N·m (matched with 2400:1 gear reduction ratio)
o ≥ 2.7 N·m (matched with 3700:1 gear reduction ratio)
6. Valve 90° (quarter turn) actuation time:
o ≤ 10 s (matched with 2400:1 gear reduction ratio)
o ≤ 16 s (matched with 3700:1 gear reduction ratio)
7. Standard gear reduction ratio options: 2400:1, 3700:1
8. Wire Sequence Definition (WSD)
| Wire Color | Core Function Definition |
| Blue | Valve open in-position switch signal |
| White | Common terminal (COM) for in-position signals |
| Yellow | Valve close in-position switch signal |
| Black | DC power positive pole (+) |
| Red | DC power negative pole (-) |
| Note: Wire sequence, color coding and wire length can be fully customized according to customer’s specific requirements. |
Ingress Protection (IP) Rating: IP67Note: IP67 dust-tight and water immersion protection performance is only achieved when the actuator is correctly assembled and firmly fixed with the matching sealed water meter housing.
Q: What pipe sizes is the KY-59 actuator compatible with?
A: The Low Noise Water Meter Gear Motor is designed for DN15 to DN50 water meter valves, with two gear reduction ratio options to match different torque requirements for various pipe diameters and working conditions.
Q: Can the wire sequence and wire specifications be customized?
A: Yes. We support full customization of wire sequence, color coding, wire length and wire gauge to fit your specific assembly, installation and control system requirements.
Q: Does the IP67 rating support long-term underwater operation?
A: Standard IP67 rating ensures the unit is dust-tight and resistant to temporary immersion in up to 1m of water for 30 minutes. For long-term submerged operation in water meter working scenarios, it must be correctly assembled with the matched sealed water meter housing to maintain stable protection performance.
Q: What power supply is recommended for the KY-59?
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 using a stable 3.6 V lithium battery power supply to balance torque performance, low power consumption and long service life.
