What is a Hydraulic solenoid valve?

Hydraulic solenoid valves are devices that supply oil to hydraulic equipment such as cylinders. There are those that are 0 or 1 that allow oil to pass through or not, and those that allow the oil supply position to be changed (such as the rod side or head side of the cylinder, which can be changed), which can be changed. In the case of things, the oil passage in the solenoid valve is called the port, and the port changes by the operation of the internal electromagnet, and is expressed as the position.
