Actuators StG 2040/2080

This powerful type of actuator is used preferably on diesel engines with medium or high power output. However, they can also be used in gas engines or gas turbines.
Properties:

  • Powerful actuating torque, identical in both directions of operation
  • Short adjustment times
  • Low current draw under load changes
  • Very low holding current
  • Insusceptible to slow fluctuations in the voltage supply
  • Contactless position return
  • Current limitation with mech. block for overheating protection
  • Can be installed in any position
  • Maintenance-free
  • Optionally with return spring
