Cleveland Controls Rotary Actuators are widely employed to position final elements such as air or flue dampers, fuel and feedwater control valves, stoker speed and variable speed drive levers. They are used for the control of boilers, incinerators, curing ovens, dryers, spray booths, evaporators, and other process unit applications.

Developed by Cleveland Controls, a leader in combustion control since 1901, these actuators perform to meet the demands of electric, electronic, and microprocessor control systems.
