Eurotherm EA12 Manual (PDF)

The Eurotherm EA12 actuator is a spring return gear driven crankshaft actuator for two position operation of dampers, valves or other equipment that require return to normal position upon power interruption. 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 Eurotherm EA12 crank actuator is also sealed in oil.
