HTS KS – IC + Valve Assemblies

Overview

The Kromschröder IC series actuators are designed for applications requiring precise, controlled rotary movement between 0° and 90°. When paired with a compatible control element, each IC actuator regulates gas and air flow rates on burner appliances for both modulating and stage-controlled combustion processes.

The IC series spans four models — IC 20, IC 30, IC 40, and IC 50 — each engineered for a distinct torque range and control ratio requirement. From compact installations on butterfly valves to high-torque applications with axial fan butterfly valves, the IC family provides a scalable actuation solution for industrial combustion systems.
