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.

It takes four piezo valves hooked to a controller to form a system that can be connected to a double-acting cylinder. Speed is controlled by maintaining a constant cylinder exhaust flow rate.

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 ...
