Figure 1 is an example of a hydraulic solenoid valve. Hydraulic solenoid valves are widely used in industries like manufacturing, aerospace, construction and many others that require hydraulic systems. The spool is the cylindrical component which serves the function of the valve by either blocking or allowing the flow of liquid through these ports, depending upon its position. The solenoid is used for sliding the spool within the valve, opening or closing the ports. The valve consists of various chambers also called ports.
The valve operates with a solenoid, which is an electric coil wound around a ferromagnetic core at its center.
