It uses an electronic energy storage system rather than a mechanical spring, allowing smoother fail-safe operation and configurable response behavior. The MFT platform enables field programming of control signals, operating ranges, and feedback outputs to match diverse building automation requirements. This actuator is commonly applied in hydronic and air-handling systems where flexibility, accuracy, and safety are critical. Key Features Electronic fail-safe functionality: Uses internal energy storage to move the valve to a safety position during power loss without a mechanical spring. MFT programmable platform: Allows configuration of control mode, signal type, operating range, and feedback to suit specific system requirements. Multiple control modes: Supports voltage, current, PWM, floating point, and on/off control from a single actuator model. Adjustable operating range: Variable start and end points enable precise matching to valve stroke and control strategy. Integrated position feedback: Provides a configurable 2–10 V feedback signal for monitoring and closed-loop control. Selectable direction of motion: Motor and fail-safe direction can be set via switches to simplify installation. Electronic overload protection: Protects the actuator throughout the full rotation range for long-term reliability. The DKRX24-MFT-T delivers the reliability and precision required for advanced modulating control with electronic fail-safe protection in professional HVAC and industrial systems.
