The working principle of the hydraulic solenoid valve is based on the combined action of electromagnetic force and liquid pressure, and changes the channel of the hydraulic fluid by controlling the movement of the spool, so as to control the flow direction and flow ‌. The hydraulic solenoid valve is mainly composed of a valve body, a spool, a solenoid coil and a spring. The valve body is provided with a plurality of channels for hydraulic fluid in and out; The spool is located inside the valve body and moves to control the opening and closing of the channel or change the flow direction of the fluid; The electromagnetic coil is wound outside or inside the valve body and generates an electromagnetic force when energized, which acts on the spool and makes it move to a new position, thereby changing the channel of the fluid. ‌

‌ The working process of the hydraulic solenoid valve can be divided into power state and power state ‌. In the energized state, the electromagnetic coil is energized to generate a magnetic field, which attracts the spool to move and changes the channel of the fluid; In the state of power failure, the magnetic field disappears, the spool recovers to the initial position under the action of the spring, and the fluid flows in accordance with the original path. This working principle enables the hydraulic solenoid valve to accurately control the flow direction and flow rate of the fluid to meet the needs of industrial automation control systems.

Hydraulic solenoid valves are widely used in hydraulic systems, pneumatic systems and industrial machinery and other fields, such as machine tools, metallurgy, shipbuilding, aviation and other industries of automation equipment. According to the function and structural characteristics, hydraulic solenoid valves can be divided into a variety of types, such as one-way valves, reversing valves, balanced valves, proportional valves, etc., different types of solenoid valves have different characteristics and scope of application.
