ICI‘s L series rotary electric actuator was designed for quarter turn valve and damper applications requiring up to 3840 lb × in torque. This heavy-duty reversing actuator has been manufactured since 1991 and is well known for its dependability in harsh applications where reliability is of utmost importance. L series actuators are equipped with hardened steel spur gears guaranteeing high efficiency, quiet operation and long trouble free life and, as in all ICI actuators, can withstand stall conditions without suffering gear failure. The heavy-duty sand-cast aluminum enclosure meets NEMA 4 specifications and has 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 gearing, 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.
