The ANT3-5.11SC actuator electrically regulates valves from the RV 111 COMAR series. The actuator connects to the valve without any play, ensuring maximum control precision even with small position changes. It is suitable for heating, air conditioning, and ventilation systems. The self-adaptive function allows the actuator to automatically adjust to the valve parameters (end positions, stroke). The actuator is continuously controlled by a 0...10V / 4...10 mA signal from the superior control unit, but also features a manual wheel for emergency manual operation. Connecting to the valve is easy and quick, requiring no tools at all. Continuous control is ensured by an integrated microprocessor. This also allows for feedback to the superior control unit. The actuator can detect valve clogging with impurities and activate a self-cleaning function. Fault reports are stored in history and can be retrieved and displayed later. The actuator is equipped with a stroke indicator. Its simple construction ensures long life and reliability. The valve adjustment time is 5 seconds. The actuator features an emergency function for power failure situations. In the event of a power interruption, the actuator resets the valve to a pre-set emergency position. The emergency position is optionally adjustable in percentage of stroke from 0 to 100%. The adjustment time for the emergency function is 8 seconds.
