Regulating Electric Actuators provide a more precise control for applications that require minute adjustments in flow or pressure. They are more costly but deliver accuracy through a closed-loop feedback system. This system, consisting of a control unit and a sensor, ensures the actuator maintains a specific motion profile. Commonly used in HVAC systems and industrial processes, these actuators can be fine-tuned with adjustable speed and position limits, allowing them to be customized for various applications.
