---

1. **Limited Torque for Heavy-Duty Applications** At 11.3 N m, it may struggle with very large valves, high-pressure systems, or valves with excessive friction (e.g., heavily corroded or oversized ball valves).

2. **No Built-in Position Feedback** Unlike some higher-end actuators, this model does not include position sensors, requiring external limit switches or encoders for precise control.

3. **Potential for Overheating in Continuous Use** While 0.9A is low, prolonged operation in high-resistance environments could lead to excessive heat if cooling is inadequate.

4. **Higher Upfront Cost Compared to Manual Valves** Automating a valve with an actuator is more expensive than using a manual ball valve, though long-term operational benefits may justify the cost.

5. **Dependence on Power Supply Stability** Voltage fluctuations or power interruptions could cause erratic operation, requiring backup power or surge protection.

6. **Maintenance Requirements** Like all mechanical actuators, it may need periodic lubrication of moving parts and inspection for wear, especially in dusty or corrosive environments.

7. **Limited Customization** The standard model may not include features like integral solenoids with fail-safe positions or advanced diagnostics found in premium actuators.

8. **Potential for Actuator Stiction** In low-flow or stagnant conditions, the actuator may bind, requiring occasional manual adjustment or a higher-quality model with anti-stiction features.

9. **No Integrated Filtering for Dirty Environments** If used in systems with particulate contamination, additional filtration may be needed to prevent damage to internal components.

10. **Learning Curve for Installation** Proper alignment with the valve and wiring can be tricky for inexperienced users, potentially leading to installation errors.
