Direct Replacement for Barber-Colman and Eurotherm Actuators
The EA73 High-Torque Actuator is a heavy-duty, industrial-grade actuator designed for high-performance control of burner systems and dampers in asphalt plant environments. Known for its durability, torque output, and compatibility, the EA73 is a trusted replacement for legacy models from Barber-Colman, Eurotherm, and Schneider Electric.
At Motion Engineering, we supply genuine and drop-in compatible EA73 actuators to support asphalt plant automation, burner positioning, and damper control. These actuators are built for continuous duty, delivering high torque output and smooth modulation in demanding applications.
Product Overview and Applications
The EA73 actuator features precision movement and high torque capability, making it ideal for use with:
- Burner air control systems
- Fuel modulation
- Damper actuation
- Valve positioning
- Temperature control loops
It’s commonly installed in asphalt plants, combustion systems, and industrial heating systems that require accurate and consistent mechanical response.
Key Features and Specifications
- High-torque output: Suitable for heavy damper loads and burner linkages
- Proportional control: Smooth, modulating movement for precise positioning
- Direct-coupled design: Reduces backlash and increases reliability
- Drop-in compatible: Replaces existing Barber-Colman and Eurotherm EA73 actuators
- Rugged housing: Built for harsh environments, including high-heat areas near asphalt plant burners
- Torque rating: 35 lb-in (4 Nm) continuous duty
- Control signal: Accepts 135-ohm input for modulating control
- Power: 120 VAC, 50/60 Hz
Reliable Performance in Harsh Conditions
The EA73 High-Torque Actuator is designed to withstand the harsh, high-temperature, and dust-laden environments commonly found in asphalt production. Its continuous-duty motor, long-lasting gears, and weather-resistant construction ensure years of reliable operation with minimal maintenance.
When installed as part of a burner control loop or damper system, the EA73 helps maintain stable combustion, reduce fuel usage, and improve process consistency.
