What is the primary purpose of a valve in a hydraulic system?

The primary purpose of a valve in a hydraulic system is to control flow. Valves are essential components that manage the movement of hydraulic fluid within the system. By opening, closing, or throttling the flow, valves ensure that the right amount of fluid reaches each part of the system at the appropriate time. This control is crucial for achieving desired movements and actions within hydraulic machinery, such as actuating cylinders or driving hydraulic motors.

While valves can also aid in changing direction or, in some cases, might contribute to the overall pressure in the system, their fundamental function centers around regulating the flow of fluid. This ensures efficient operation and responsiveness of the hydraulic system, allowing for precise control over its various elements and applications.
