The ANT3-11.11 servo drive electrically regulates valves from the RV 122 BEE series. The drive is connected to the valve without any backlash, so maximum regulation accuracy is ensured even with small changes in position. It is suitable for heating, air conditioning and ventilation systems. The self-adaptive function enables the drive to automatically adapt to the valve parameters (end positions, stroke). The drive is continuously controlled by a 0,,,10V / 4...10 mA signal from the superior control unit, but it also has a handwheel for manual control in case of emergency. Connection to the valve is quick and easy and requires no tools.

Continuous control is provided by an integrated microprocessor . It also enables feedback to the superior control unit . The drive is able to recognize the valve clogging with dirt and start the self-cleaning function . Error messages are saved in the history and can be recalled and displayed later.

The drive is equipped with a stroke indicator. The simple design ensures long life and reliability. The adjustment time of the valve is 10 s.
