What are the characteristics and function of the directional control valve?

How do directional control valves actually work?
Directional control valves provide precise control of flow in hydraulic lines. They provide several functions that are critical to the efficient operation of a hydraulic system.

The first function of a directional control valve is to control the direction of flow. It can divert flow from a source to an actuator or from an actuator to the return line. This allows movement in different directions, such as forward and reverse movement of a hydraulic cylinder or rotation of a hydraulic motor.

Another important function of the directional control valve is to block the flow. In certain situations, it is necessary to stop the flow. This applies, for example, when a certain function is not needed or when maintenance work is being performed on a part of the system.

The directional control valve can block the flow and prevent the hydraulic fluid from entering a certain area. This allows maintenance work to be carried out without paralyzing the entire system.
