The lift actuator is installed directly onto the valves without requiring any additional accessories. Installation is easy and quick. It is designed for VVG549.. valves in HVAC applications. The actuator is controlled by a continuous signal with automatic reset to electric operation. Any control signal from the offered options can be selected for the actuator. One controller can be superior to up to ten actuators, allowing this model to be connected in parallel. The actuator is equipped with a return function thanks to a spring. The actuator receives a feedback signal at terminal U. During installation, the actuator performs self-calibration and determines the end positions the valve spindle can reach. It also immediately detects the actual stroke value of the valve dependent on force. This data is then stored for later operation. The actuator is also equipped with a foreign body detection function, which can recognize if the valve body has been blocked by a foreign object. The actuator will then make three attempts to release it, and if unsuccessful, it will start signaling a fault with LED indication. The actuator's design integrates forced control Z (Z mode), which is prioritized over automatic mode.
