- May need **custom modifications** for non-standard valve sizes or mounting requirements, adding to installation time and cost.
3. **Dependence on Pneumatic Supply**
- Relies on a **stable compressed air source**, which may not always be available or may require additional infrastructure (e.g., air dryers, filters).
- Air leaks or pressure drops can affect performance, requiring **regular maintenance of the pneumatic system**.
4. **Limited Customization for Non-Standard Applications**
- While modular, the ADVU-25 series may not support **highly specialized or non-standard valve types** without additional adapters or custom work.
- Some advanced features (e.g., custom position profiles) may require **additional programming or third-party software**.
5. **Potential for Higher Maintenance in Dirty Environments**
