1 Concept Wechsel ein-auf zweispaltig

Compact actuator for the operation of final control elements with preferably 90° rotary movement such as flaps, cocks, etc. The torque is transferred via a lever / linkage bar assembly or the actuator is directly coupled to the cock flange. A special power electronic unit controls the actuator. The electronic unit serves as the interface between actuator and control system. During continuous positioning the power electronic unit varies the motor torque steplessly until the actuator force and the restoring

process forces are balanced. High response sensitivity and high positioning accuracy with short positioning time ensure an excellent control quality and a long actuator life.

Note The ANSI information appears in parentheses after the SI-information.
