The Eurotherm EA50 medium torque actuator is ideal for proportional positioning of a fuel valve, butterfly valve, damper and similar applications. Units are available with either fixed or adjustable speed. Timing of adjustable speed units can be increased (decreasing the speed) by turning a slotted adjustment screw on the outside of the case. Adjust range is approximately ten times rated. Standard features include a 100ž feedback slidewire and a single SPDT switch. All models, except those with transformers, are UL/cUL listed.
