Ii. Working Principle
Based on the principles of electromagnetic induction and electromagnet attraction: When powered on, the coil generates a magnetic field, attracting the moving iron core to overcome the spring force and move the valve core, thereby achieving the reversing/on-off of the oil circuit. When the power is cut off, the magnetic field disappears, the spring returns to its original position, and the valve core returns to cut off/switch the oil circuit, completing one action cycle. The oil-immersed design reduces temperature rise, enhances response speed and extends lifespan.

Iv. Function and Role
Drive the valve core of the hydraulic valve to act, achieving the on-off, reversing or flow regulation of the oil circuit
As an electro-hydraulic conversion actuator, it receives electrical control signals and converts them into hydraulic actions
Work in conjunction with the controller to achieve automated control, enhancing the system’s response speed and accuracy

V. Precautions for Installation and Use
Before installation, clean the coil and valve interface, and check that the seals are intact to prevent impurities from entering
Connect by polarity/phase. For DC coils, distinguish between positive and negative poles; for AC coils, check the frequency (50/60Hz).
The torque complies with the specifications to prevent damage to the threads or sealing surfaces
Avoid long-term overload or frequent on-off of the coil to prevent overheating and burnout
Regularly check the insulation resistance and sealing. Replace them in time if any leakage or abnormal heating is found
After wiring, ensure proper protection to prevent oil from entering the connector and causing a short circuit
