Proportional valves adjust flow rates for hydraulic systems. These valves are typically used in applications where more control and adjustments are needed beyond a standard directional control valve.

Hydraulic systems use a central "variable displacement pump" that pressurizes fluid, and valves direct the flow of fluid to "actuators," which move tools such as shovels and buckets in excavation ...

Hydraulic System Analysis," Penton Publications ... the pump continues to discharge fluid, and that flow must be absorbed by fluid conductors, valves, actuators, and other components.

Hydraulic components and systems remain a vital part of most machines ... cylinder and a number of electronically controlled valves and ECU (electronic control unit) with a software control ...
