Mid-Torque, Non-Spring Return Actuator for Industrial Combustion Control
The EA57 Actuator is a reliable, medium-torque actuator designed for precise control of burners, valves, and dampers in asphalt plants and other high-demand industrial environments. Designed as a direct retrofit for Barber-Colman, Eurotherm, and Schneider Electric units, the EA57 offers responsive modulation and dependable positioning without the use of a return spring.
At Motion Engineering, we supply the EA57 as a plug-and-play solution for burner control upgrades or replacements. Its compact design, stable response, and smooth proportional control make it well-suited for applications requiring consistent combustion management with minimal maintenance.
Designed for Industrial Burner Systems
The EA57 actuator enables smooth, controlled movement in various plant automation scenarios. It’s commonly used in:
- Fuel and air ratio systems
- Damper and valve modulation
- Combustion temperature balancing
- Burner control applications in asphalt production
Its non-spring return mechanism ensures precise positioning for operations where consistent modulation is critical to process performance.
Specifications and Technical Features
- Torque output: 25 lb-in (2.8 Nm) for medium-duty requirements
- Control input: 135-ohm signal for smooth modulating operation
- Power: 120 VAC, 50/60 Hz
- Direct-coupled output: Simplifies installation and reduces mechanical play
- Sturdy industrial build for operation near heat-intensive equipment
- Compatible with older Eurotherm and Barber-Colman systems
- Long-lasting motor and internal components designed for ongoing duty cycles
Durable and Built for Demanding Conditions
The EA57 actuator is built to perform in temperature-variable, dust-heavy environments, making it a strong choice for asphalt plants and industrial burners. Its non-spring return configuration holds position without drift and is especially valuable in systems that require tight feedback loops and uninterrupted modulation.
Operators benefit from reduced wear, low drift, and the ability to maintain process stability without constant recalibration or service interruptions.
