Which component directs hydraulic fluid to various ports based on steering input?

Directing hydraulic fluid to different ports based on steering input is the job of a directional control valve. In a hydraulic steering system, the pump delivers pressurized fluid to the valve, and the valve’s internal spool shifts with steering input to connect pressure to one side of the cylinder while routing the fluid from the opposite side back to the reservoir or tank. This selective routing makes the cylinder extend in one direction or the other, producing the desired steering movement. Flow control valves only limit speed by restricting flow, not change its path; the reservoir simply stores fluid; the relief valve protects the system from overpressure. So, the component that routes fluid to the correct ports based on steering input is the directional control valve.
