Discharge the cleaning oil after the flushing is qualified, and inject qualified hydraulic oil into the oil tank through the precision filter.


2. The electro-hydraulic servo valve is a precision product of mechanical, hydraulic and electrical integration. Before installation and commissioning, it is necessary to have relevant basic knowledge, especially to read and understand the product samples and instructions in detail.


3. The installation position of the electro-hydraulic servo valve shall be as close to the hydraulic actuator as possible, and the hose shall be used as little as possible between the servo valve and the actuator. All these are to improve the frequency response of the system.


4. The filter used by the press is generally 5-10um according to the requirements of the electro-hydraulic servo valve on the filter accuracy.


5. The inner wall material or coating of the oil tank shall not be changed into the pollution source of oil all the year round. The oil tank material of the hydraulic control system shall be stainless steel.
