This manual covers safety precautions, design considerations and selection criteria for the VT317 3‑way solenoid valve. It explains the required safety levels (注意, 警告, 危险), applicable standards and the need for qualified personnel during installation and maintenance.
Detailed sections describe installation steps, piping preparation, wiring connections, oil lubrication, required gas source quality, permissible operating environments, routine maintenance, product‑specific notes and a comprehensive fault‑diagnosis guide with corrective actions. This manual is written in Chinese.
| Pressure range | -101.2 kPa to 0.1 MPa |
|---|---|
| Minimum operating temperature | > -10 °C |
| Leakage voltage limit (DC coil) | ≤ 2 % of rated voltage |
| Leakage voltage limit (AC coil) | ≤ 20 % of rated voltage |
The manual classifies safety items into three levels: 注意 (caution), 警告 (warning) and 危险 (danger).
The valve should be switched at least once every 30 days to avoid performance degradation.
Use Turbine Oil No. 1 (ISO VG32) without additives for lubrication.
The polarity must be observed; incorrect polarity will prevent the valve from switching.
