The EA50 and EA60 medium torque actuators are ideal for proportional position-
ing 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 100Ω feedback slidewire and a single SPDT switch.
All models, except those with transformers, are UL/cUL listed. The EA50 and
EA60 are compatible with the VB-7000 and VB-9000 valves in this catalog.
