When troubleshooting electro-hydraulics with a servo valve, what type of system is it likely to be?

When troubleshooting electro-hydraulics with a servo valve, it is most commonly associated with a closed loop system. This type of system employs feedback to continuously monitor and adjust the output based on the desired setpoint. In a closed loop system, the servo valve regulates the flow of hydraulic fluid to accurately control the position or speed of an actuator.

The presence of feedback is crucial in a closed loop system because it allows for real-time adjustments. This ensures that the system can compensate for any disturbances or changes in operating conditions, maintaining optimal performance and precision that is fundamental in applications requiring precise control, such as in robotics or CNC machinery.

In contrast, an open loop system lacks feedback, meaning it operates based solely on predetermined settings without real-time adjustments. Systems controlled by air might utilize pneumatic applications instead of hydraulic, and those without feedback do not constitute a servo mechanism, as servos inherently depend on feedback to correct deviations from the desired behavior. Therefore, the alignment with feedback and real-time adjustments underscores why a closed loop system is the correct answer in this context.
