The Eurotherm EA53-1 medium torque actuators are 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 100Ω feedback slidewire and a single SPDT switch.
All models, except those with transformers, are UL/cUL listed.
The EA53-1 are compatible with the VB-7000 and VB-9000 valves.
