The Water meter gear motor is the core actuation component of smart water metering systems. It consists of a precision micro motor, gear reducer, and transmission mechanism, engineered to drive ball valves or globe valves to complete 90° quarter-turn rotation or linear actuation.
This Water meter gear motor is available in two mainstream control interface configurations: 2-wire and 5-wire. The 2-wire type judges valve in-position status via current feedback or time control, while the 5-wire type, equipped with dedicated in-position switches, delivers higher positioning accuracy and more reliable real-time status feedback. As the intelligent valve control core of smart water meters, it executes valve opening and closing actions strictly according to system instructions, upgrading traditional water meters from passive metering-only devices to active intelligent water flow control and management units.
The Water meter gear motor is a high-torque, low-power electric gear motor, purpose-built for medium-caliber smart water meters and industrial fluid control scenarios, with stable performance and strong load capacity for long-term continuous operation.

Q: What pipe and valve sizes is the KY-04 gear motor compatible with?
A: Equipped with a 6200:1 gear reduction ratio and ≥4 N·m high output torque, the KY-04 is fully compatible with DN15, DN20, DN25 and DN32 motorized valves for smart water meters and other medium-caliber fluid control applications.
Q: What is the difference between 2-wire and 5-wire control configurations?
A: The 2-wire type features a simplified structure and lower cost, judging valve position via current or time control. The standard 5-wire KY-04 has built-in in-position switches, delivering higher positioning accuracy, real-time valve status feedback, and more reliable control for smart water metering systems.
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.
