Honeywell Kromschroder IC50 High Torque Actuators

  • High-torque rotary actuator
  • IC50 auto/manual mode to facilitate valve setup
  • Designed to direct-couple to the BV and VFC-series valves
  • Approvals: CE, CSA


The actuators are designed for all applications that require precise, controlled rotary movement between 0° and 90°. In In conjunction with a control element, they are suitable for regulating flow rates on gas and air appliances for modulating or stage controlled combustion processes.

IC50 Actuators are high-torque rotary actuator with 3-point step or continuous control equipped with auto/manual switch for commissioning.  Features: precision servo motor, auto/manual mode to facilitate valve setup, adjustable cams for high and low positions, plus two free-floating cams and optional feedback potentiometer.

IC 50 is designed for applications with high torques of up to 30 Nm.

Difference of IC20, IC40 and IC50:

IC 20, IC 50 with voltage-free limit switches, Automatic/Manual mode changeover, position feedback and externally readable position indicator.  IC 50 also with selectable direction of rotation.  IC 40 for complex applications with programmable functions for flexible adjustment to the process, with statistics and fault history to support service personnel.

Running time:
IC 20: 7.5 to 60 s
IC 50: 3.7 to 60 s
IC 40: programmable

Mains voltage:
