The SD series compact rotary electric actuator was specifically designed for valve sizes from ¾” to 2½” and dampers that do not exceed the rated torque of the actuator. These heavy-duty reversing actuators develop 200 lb·in (model SD) and 300 (model SDX) lb·in torque and rotates form 0 to 90 in 5 seconds. The spur gear drive train has been designed for severe applications and, as in all ICI actuators, can withstand stall conditions without suffering gear failure. The heavy-duty die-cast aluminum enclosure meets NEMA 4 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 motor with thermal overload protection, two limit switches wired for light indication, stainless steel fasteners, captured cover screws and 300 series stainless steel output drive, spring friction brake, non-declutching manual override and position indicator.
