The working principle of the hydraulic valve is based on the relative movement between the spool and the valve body, and the pressure and flow in the hydraulic system are adjusted by changing the flow area or throttle length of the valve port. Take the relief valve as an example, when the system pressure exceeds the set value, the relief valve will automatically open, and the excess oil will be discharged back to the tank, so as to keep the system pressure constant. This pressure regulation function is of great significance in preventing system overload and protecting equipment safety. Hydraulic valves are widely used in various mechanical equipment, such as construction machinery, mining machinery, CNC machine tools, etc., and their precise control ability and high reliability provide a strong guarantee for the normal operation of these equipment.
