Proportional hydraulic valves represent the ideal solution when a continuous and precise control of the variables of a hydraulic circuit is required. Unlike on-off valves, these valves allow progressive modulation of pressure, flow rate and fluid direction, according to an electrical control signal, ensuring high dynamic performance and repeatability of control.

On fluid-hub you will find a complete range of proportional valves designed for industrial applications where precision, reliability and integration with electronic control systems are essential. The use of these valves makes it possible to improve system efficiency, reduce hydraulic shocks and optimize the behavior of actuators even under variable load conditions.

The category includes the following main subcategories:

• Directional proportional valves, used to control the direction and speed of actuator movement through continuous adjustment of the flow passages.

• Flow control proportional valves, ideal for precise regulation of the speed of hydraulic cylinders and motors, even when the load varies.

• Pressure control proportional valves, designed to manage pressure levels within the circuit accurately and stably.

Proportional valves naturally integrate with digital drivers, sensors and PLC systems, making them particularly suitable for applications in automation, machine tools, presses and complex systems. Alternatively or in combination, they can operate together with on-off valves, filling valves and valve spare parts, effectively completing any hydraulic architecture.
