Barber Colman EA50-A Series Analog Input Medium Torque Non-Spring Return Rotary Actuators

EA50-A series actuators are ideal for proportional position of fuel valves, butterfly valves, dampers and similar devices. EA52-A and EA56-A models have an adjustable hydraulic brake that provides up to a 10:1 speed reduction. A constantly powered field winding serves as an electric brake to hold the actuator in position when no movement is required. These actuators stay in position when power is removed. The EA50-A is compatible with the VB-7000 and VB-9000 valves in this catalog.
