The working principle of hydraulic valve is mainly based on fluid mechanics and mechanical control principles. Taking the reversing valve as an example, when the electromagnet is energized, the armature is attracted and pushes the spool to change the opening and closing state of the valve port, thus changing the direction of oil flow. Hydraulic valves are widely used in various mechanical equipment, such as excavators, cranes, injection molding machines, etc. In these equipment, the hydraulic valve precisely controls the flow of oil to achieve various actions of the equipment, such as lifting, rotation, expansion and so on. At the same time, the hydraulic valve can also protect the system safety and prevent the occurrence of abnormal situations such as overload and overheating.
