Datasheet
Technical features
| Manufacturer warranty | 2 years |
|---|---|
| Overload Protection | In the event of a valve jam, the power supply will automatically shut down to avoid any further damage to the valve or actuator. |
| Operational Safety | To ensure the safe operation of the motor, the motor winding includes a temperature control switch that can detect the motor's temperature and prevent overheating issues. |
| Voltage Protection | The system includes protection against both high and low voltage scenarios. |
| Applicable valve | Ball Valve; Butterfly Valve |
| Anti-corrosion Protection | The enclosure is made of epoxy resin and is NEMA 4X certified, with the option for customized painting to meet customer needs. |
| Ingress Protection | IP67 is standard, Optional: IP68( Maximum 7m; Max: 72 hours) |
| Fireproofing Grade | A heat-resistant enclosure that meets the necessary criteria in different situations where fire protection is required. |
| 360° Position Indicator | Adopts high strength, anti-sunlight and RoHS-compliant plastic 3D window indicator. Users are able to observe the stroke position of the actuator within the 360° visual angle as thereis no dead angles. |
