Introduction
LME620-AN
LME620-AI
Actuator for the operation of final control
RSD10
RSD20
elements with preferably linear movement. The
RSD50
thrust rod transfers the force directly to the final
RSD100
control element.
A continuous electronic unit controls the
actuators. The special electronic unit serves as
the interface between actuator and control
system.
Electric linear actuator for
operating final control elements.
Rated force
4 to 100 kN (900 to 22500 lbf)
