Closed water meter actuator usually also called electric control valve, is a key executive component in the smart water system.
Closed water meter actuator 's function is to receive instructions from the smart water meter or control system and automatically open or close the water circuit, thereby realizing automatic control of water flow.
Closed water meter actuator is not an independent water meter itself, but an electric drive device installed on the pipeline behind the water meter. Waterproof rating of closed water meter actuator is IP66.
| 1. Rated working voltage | 3.6V |
| 2. Working voltage range | 2.5-5V, (the higher the voltage, the greater the torque and the shorter the service life) |
| 3. No load working current under rated working voltage | < =25mA (23 ℃ under normal temperature) |
| 4. Locked rotor current under rated working voltage | about 450mA (300 motor) |
| 5. Output torque under rated working voltage | ≥ 1.8N.m (24001) ≥ 2.5N.m (3400:1) |
| 6. On (off) time under rated working voltage | ≤ 10s (24001) ≤ 15s(3400:1) |
| 7. Reduction ratio | 24001 (applicable to DN15-20) 3400:1(applicable to DN25) |
| 8. Definition of line sequence |
I. Blue (in place switch signal, open valve) II. White (in place signal common terminal) III. Yellow (in place switch signal, valve closing) IV. Black (positive) V. Red (negative) (due to the different installation and use directions of the customers, sometimes it is the opposite between opening and closing, which needs to be determined by the customers themselves according to the situation.) |
| 9. Waterproof grade | IP66 |
Q: Can the KY-24 closed water meter actuator be used in outdoor environments?
A: Yes. The product has a waterproof rating of IP66, which can effectively prevent dust and water intrusion, and is suitable for outdoor pipeline installation and use.
Q: How to choose the appropriate reduction ratio for different pipeline specifications? A: Choose according to the pipeline DN specification: the reduction ratio of 2400:1 is applicable to DN15-20 pipelines, and the reduction ratio of 3400:1 is applicable to DN25 pipelines, which can ensure sufficient output torque to control the water circuit stably.
Q: What factors will affect the service life of the actuator?
A: The working voltage is the key factor. The product’s working voltage range is 2.5-5V, and the higher the voltage, the greater the torque but the shorter the service life. It is recommended to use the rated working voltage (3.6V) to ensure the balance between performance and service life.
Q: Is the closed water meter actuator an independent water meter? How to install it?
A: No, it is not an independent water meter. It is an electric drive device that needs to be installed on the pipeline behind the water meter, and it can realize automatic control of water flow after connecting with the smart water meter or control system.
