DFK type electric valve controller is a product that is used in conjunction with valve actuators. It has the characteristics of low-voltage control circuit, safe operation, reliable control, accurate and intuitive opening degree indication, etc.
This manual describes the DFK electric valve controller, a low‑voltage DC control device for opening and closing electric valves. It outlines key features such as accurate opening‑degree indication, compact housing, and multiple status indicator lights.
The document includes technical data, front and rear panel component descriptions, operating principles, and step‑by‑step installation and adjustment procedures, as well as debugging instructions and safety precautions. This manual is written in Chinese.
| Working voltage | 220V / 50Hz |
|---|---|
| Control voltage | 380V / 50Hz |
| Control power | <1.1 kW |
| Operating temperature range | -20~40℃ |
| Relative humidity | ≤80% (20±5℃) |
The controller operates at 220 V, 50 Hz.
When the valve is fully open, adjust the potentiometer so the opening‑degree indicator shows 100%.
The accident/protection red indicator lights up and the buzzer sounds.
Verify that all wiring connections are correct, especially the A.B.C.N power terminals and PE grounding.
