Actuator for 2-way and 3-way valves and controllers with continuous or non-continuous output. The actuator features a brushless DC motor, controlled by an electronic SUT (Sauter Universal Technology) unit, and is equipped with maintenance-free gearing and load-dependent electronic shut-off. It automatically detects the control signal used (continuous/switching) and displays it via a two-colour LED indicator. The actuator automatically adjusts to the valve stroke value. Even in the event of a power failure, the actuator remembers its position thanks to absolute distance measurement. A range of parameters can be set on the actuator via coded switches.

Installation is possible from an upright vertical to a horizontal position and is very easy. Upon receiving the control signal, the spindle automatically connects. Thanks to numerous adapters, the actuator can also be mounted on valves from other manufacturers. During operation, the actuator is very quiet.
