170 Degree Travel limit, Counter Clockwise Return, 20 sec travel, 60 in-lbs torque, 240Vac/60 Hz
The Eurotherm EA12-3 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 EA12-3 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. The Model EA12-00000-000-0-00 is UL/CSA listed. All others models are UL/cUL listed. The EA12 is compatible with the VB-7000 and VB-9000 valves in this catalog.
