Build Your Own Actuator

K Series

K Series

This series of heavy-duty reversing actuators were developed in 1995 and went into production early in 1996. ICI‘s K series rotary electric actuator is a machine that was designed to automate quarter turn equipment requiring up to 27300 lb × in (2275 lb × ft) torque. The K series actuators are equipped with a combination spur gear-worm/worm gear drive train providing efficient and quiet operation, resistance to back driving and long maintenance free service. The heavy-duty sand-cast aluminum enclosure meets NEMA 4 specifications and is equipped with a thermally bonded ultraviolet resistant polyester powder coating that not only enhances its appearance but is also a tough corrosion resistant coating.

Standard equipment includes 115Vac-1ph continuous duty motor with thermal overload protection, heavy duty hardened steel spur/worm with bronze worm gear, electronic torque sensor, two limit switches wired for light indication, stainless steel fasteners, 300 series stainless steel output drive, declutching manual override with hand wheel, visual position indicator and polyester powder coating.
