How to adjust the pressure of cylinder unloading valve

1. First, we need to find the position of the cylinder unloading valve. Need to find the location of the cylinder unloading valve.

2. Secondly, the pressure adjusting screw is located on the cylinder unloading valve. This screw is located on the valve body and can be rotated by a voltage regulator or wrench.

3. Then, using a voltage regulator or wrench, rotating the pressure regulating screw counterclockwise can reduce the pressure of the unloading valve of the steel cylinder, and rotating the pressure regulating screw clockwise can increase the pressure of the unloading valve of the steel cylinder.

4. Finally, after each adjustment, the performance of the hydraulic system should be tested to ensure that the adjusted pressure meets the requirements. Observe the movement of the hydraulic cylinder and the stability of the hydraulic system to ensure that there is no abnormality.
