Overview of EHA Closed System
EHA (Electro-Hydraulic Actuator) is a product combining AC servo technology and hydraulic technology; it has the dual advantages of the flexibility of motor (servo) control and the large output force of hydraulics; it is called the Direct Drive Volume Control system; abroad, it is sometimes referred to simply as the "valveless system".
Closed system: The working oil directly returns to the oil pump after passing through the actuator. The volume of the oil is fixed and fills all hydraulic components in the system; it is completely closed, with no external contaminants entering the system; the oil remains as clean as when it was first injected; integrated valve block components realize different circuits to meet multi-functional requirements.
