Electro-Hydraulic Actuators: Precision and Power for Modern Valve Control
On this page
Electro-hydraulic actuators are innovative devices that combine the precision of electrical systems with the power of hydraulics. They operate valves by using pressurized hydraulic fluid, but their primary energy source is electrical. This dual-functionality makes them an efficient and reliable choice in various industrial applications.
Electro-hydraulic actuators can be paired with both linear and rotary valves, depending on the application. They are particularly suited for situations requiring high torque or thrust, rapid operating speeds, or fail-safe mechanisms. This versatility makes them a popular choice across industries.
How Electro-Hydraulic Actuators Work
Electro-hydraulic actuators utilize electrical power to energize a motor, which drives a hydraulic pump. The pump generates pressurized fluid that activates a hydraulic actuator to control valve operations. These systems are self-contained, eliminating the need for an external hydraulic power unit. This integrated design simplifies system construction and enhances safety and reliability.Electro-hydraulic actuators can be paired with both linear and rotary valves, depending on the application.

Advantages of Electro-Hydraulic Actuators
Electro-hydraulic actuators offer a range of benefits, making them superior to traditional hydraulic systems in many scenarios. Here are the key advantages:1. High Power Density
Electro-hydraulic actuators deliver significant power in a compact design, allowing them to handle loads up to 4,800 pounds. This makes them suitable for demanding applications where conventional hydraulics may fall short.2. Low Maintenance Requirements
Thanks to their self-contained nature, these actuators require minimal maintenance compared to traditional hydraulic systems. This reduces downtime and overall operational costs.3. Versatility and Flexibility
Electro-hydraulic actuators are highly adaptable. They can be installed in various configurations and locations without relying on additional components. Their design flexibility empowers engineers to create efficient and customized systems tailored to specific needs.4. Precision and Scalability
These actuators provide exceptional precision and can be scaled for virtually any force or application. They are ideal for projects that demand exact control over speed, stroke length, or applied force.5. Programmability and Diagnostics
Electro-hydraulic actuators can be programmed, networked, and diagnosed with ease. Engineers and operators have complete control over performance parameters, enabling quick adjustments and system optimization.6. Quiet Operation
Unlike traditional hydraulic systems, which are notoriously noisy, electro-hydraulic actuators operate quietly. This feature is particularly valuable in environments where noise reduction is essential, such as medical facilities or noise-sensitive industrial settings.7. Cost-Effectiveness
By combining the benefits of hydraulics and electrical systems, these actuators offer a cost-effective solution. Their efficiency and reduced reliance on external components help save on both installation and operational expenses.Applications of Electro-Hydraulic Actuators
