The corrosion-resistant electric actuators are available in a variety of quarter-turn reversing, quarter-turn reversing spring return, and linear drive models. The reversing actuators are designed for use with all ball and butterfly valves up to 24 percent in size, provide torque outputs from 300 to 13500 in. lbs., and are available with positioners for special on/off or modulating requirements. The electric actuators are designed for use with all ball and butterfly valves up to 8 percent in size, provide torque outputs from 450 to 2300 in. lbs, and are available with a clockwise or counter-clockwise spring return depending upon application requirements. The linear drive actuators easily adapt to most rising stem designs, provide up to 4400 lbs. down/up force, and up to 4 percent stem travel for diaphragm valves. A variety of options such as positioners, extended duty motors, 0-90 degrees to 180 degrees,feedback potentiometer, two additional auxiliary switches, local control stations, 12/24 VDC and VAC, 120/230 VAC (50/60 Hz), and 3 phase w/230 VAC, 380 VAC, or 460 VAC (50/60 Hz) are available depending upon the model selected.
