The SD series compact rotary electric actuator was specifically designed for valve sizes from to 2 and dampers that do not exceed the rated torque of the actuator. These heavy-duty reversing actuators develop 200 lbin (model SD) and 300 (model SDX) lbin torque and0 to 90 in 5 seconds. The spur gear drive train has been designed for severe applications and, as in allactuators, 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 includesmotor with thermalprotection, 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 manualand position indicator.
