Precision-machined cylindrical component that regulates fluid flow in hydraulic valves through axial movement.
The spool body is the core moving element within a precision hydraulic valve, typically a ground and polished cylindrical component with precisely machined lands and grooves. It slides axially within the valve bore to open, close, or meter fluid passages between ports, controlling direction, flow rate, and pressure of hydraulic fluid in systems requiring high accuracy and repeatability.
