The Eurotherm EA12-83 hardened steel crankshaft is driven through a train of precision hobbed gears. The actuator is driven by a shaded pole motor that is completely submerged in oil and sealed in an aluminum case to assure long life and minimum maintenance. The gear train of the EA12-83 crank actuator is also sealed in oil.

Working in conjunction with primary loop controllers, these power units are ideal for ON-OFF control of valves and dampers. The EA-12 travel time is 20 seconds and its travel limit is 170 degrees clockwise. The spring return is counterclockwise to the original position when de-energized.
