The EA55 Barber Colman medium torque actuator is ideal for proportional positioning of a fuel valve, butterfly valve, damper and similar applications. Timing can be increased (decreasing the speed) by turning a slotted adjustment screw on the outside of the case.
Standard features include a 100 ohm feedback slidewire and a single SPDT switch. All models, except those with transformers, are UL/cUL listed. Askco also stocks crank arms, pushrods, and swivel connectors for EA medium and high torque actuators
