This instruction manual introduces the safety, design, selection, installation, piping, wiring, lubrication, air source, operating environment, maintenance and inspection, product specific precautions, fault and countermeasures of SY series electromagnetic valve.
This manual provides safety and design guidelines for the SY series electromagnetic valve, including warnings, cautions and hazard symbols. It explains the required air source, operating environment and the limits for pressure and temperature.
Installation, piping, wiring, lubrication and maintenance procedures are described in detail, together with troubleshooting steps and recommended corrective actions for common faults such as coil overheating or leakage. This manual is written in Chinese.
| Protection rating | IP65 |
|---|---|
| Operating voltage | AC200V / AC220V |
| Torque for M2 screw (SY3000) | 0.16 N·m |
| Torque for M3 screw (SY5000) | 0.8 N·m |
The manual uses three symbols: Caution (注意), Warning (警告) and Danger (危险).
Use the torque values specified for each model, e.g., 0.16 N·m for SY3000 M2 screws and 0.8 N·m for SY5000 M3 screws.
Reduce the applied voltage to stay within the rated range and ensure adequate cooling as described in the maintenance section.
No, the valve is not designed for emergency shut‑off; a separate safety device must be used for that purpose.
