The 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 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.

Features:

  • Spring return two position operation
  • 60 in-lbs torque – 20 sec travel
  • Oil immersed motor and gear train
  • Compatible with VB series valves
