Eurotherm EA71 Datasheet (PDF)
Barber Colman Old Model #: EA71-00000-000-0-00
90 Degree Travel Limit, 20 sec travel time, 550 in-lbs torque, contact controlled, 120Vac/60Hz, 100 ohm slidewire feedback
These Eurotherm EA71 workhorses have the brute force to handle the big job such as a heavy damper, globe valve, blast gate or air/gas valve.
It can be used for vortex control and hydraulic coupling and will drive a speed changing screw or slide gate re-quiring a torque proportional actuator.
A solenoid brake holds the actuator in position when no movement is required.
These actuators stay in position when power is removed. NEMA 4 versions are available.
The EA71 is compatible with the VB-7000 and VB-9000 valves.
