Directional control valves are the workhorses heavily relied upon in the worlds of hydraulic circuits and machinery as well as pneumatic systems because of the way they allow fluids to flow into specific pathways from one or multiple sources. The most basic configuration is a spool inside a cylinder where the movement of the spool is what permits or restricts the flow of fluids through it. An actuating force must be applied to operate the valve and move it from normal (or neutral) position to working position. More complex control valves can have more than two basic positions by have multiple working positions.
