Eurotherm EA20 Datasheet (PDF)

The Eurotherm EA20 is working in conjunction with primary loop controllers, these low torque non-spring return actuators will proportionally position fuel valves, butterfly valves, dampers or other similar devices. The output shaft moves in both directions and can stop at any point in the stroke. The hardened steel crankshaft is driven through a train of precision hobbed gears sealed in oil. This reliable actuator is driven by a shaded pole motor completely submerged in oil and sealed in an aluminum case, minimizing maintenance.
