One of the primary functions of valves in a hydraulic system is to control the flow of hydraulic fluid. Valves regulate the direction and volume of fluid moving through the system, ensuring that hydraulic pressure can be directed to the appropriate components in a controlled manner. This control is essential for the operation of various hydraulic actuators, such as cylinders and motors, enabling them to perform their intended functions effectively.

By manipulating the flow, valves can start, stop, or modify the speed of the hydraulic fluid, thereby influencing the operation of the entire system. This ability to precisely manage flow is critical in applications where timing and position are vital for operational efficiency and safety.

In contrast, other functions mentioned, such as storing hydraulic fluid or generating pressure, are carried out by different components in a hydraulic system like reservoirs and pumps, respectively. Valves focus specifically on flow control, which is fundamental for maintaining the desired operation of hydraulic machinery.
