Proportional Directional Valves: Precision Control for Modern Hydraulic Systems

Proportional directional valves are significant components for modern hydraulic systems by providing accurate control of flow and pressure of hydraulic fluid. They differ from basic on/off valves in that they will vary the flow proportionally to an input signal, which leads to a more efficient operation of a machine than if the nozzle did not share this capability. They are found frequently in applications that require fine motion control, such as construction equipment, industrial automation, and mobile equipment. Proportional directional valves result in higher accuracy and lower energy losses, which results in higher system performance and higher system reliability. While directional valves are only a subset of hydraulic valves, they deliver precision, flexibility, and efficiency to hydraulic fluid power technology.
