1. Cleanliness requirements

1. The hydraulic system where the servo valve is installed must be thoroughly cleaned.

2. Before the servo valve inlet of the oil inlet, an oil filter with a nominal filtration accuracy of not less than 10 must be configured.

Second, installation requirements

1. The surface roughness value of the mount should be less than Ra1.6, and the surface unevenness should not be more than 0.025mm.

2. It is not allowed to manufacture the mount with magnetic materials, and no obvious magnetic field interference is allowed around.

3. The installation working environment should be kept clean, and lint-free cloth or special paper should be used when cleaning.

4. Do not connect the imported oil and oil return port incorrectly.

5. Check whether the sealing rings of each oil port on the bottom surface are complete.

6. The maximum current of each coil should not exceed 2 times the rated current.

7. The fuel tank should be sealed, and stainless steel plate should be selected as much as possible, and refueling and air filters should be installed on it.

8. It is forbidden to use twine, adhesive and sealing tape as sealing materials.

9. The flushing plate of the servo valve should be removed before installation and saved for future maintenance.

10. For long-term working hydraulic systems, larger capacity oil filters should be selected.

11. The dynamic servo valve should add a flutter signal in use, and some also require oil drainage to be directly returned to the oil tank, and the servo valve must also be installed vertically.

12. The double spray servo valve requires oil first and then electrical signal.
