ICI’s M series rotary electric actuator was designed for quarter turn valve and damper applications requiring up to 1500 lb·in torque. This heavy-duty reversing actuator has been manufactured for over twenty years and has achieved an impeccable reputation for reliability in applications requiring repeated superior performance year after year. This machine has a hardened steel spur gear drive train 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 7 specifications and has a thermally bonded ultraviolet resistant polyester powder coating that not only enhances its appearance but also is a tough corrosion resistant coating.
Standard equipment includes 115Vac-1ph 25% duty cycle motor with thermal overload protection, declutching manual override with hand wheel, two limit switches wired for light indication, stainless steel fasteners, 300 series stainless steel output drive, polyester powder coating and spring friction brake.
