What Is a Spool Valve?
A spool valve is a valve shaped like a spool, used for fluid control.
It is employed in fluid control and fluid pipelines to change the pathway of fluids or regulate flow. Typically, a spool valve operates by the movement of a spool-like plug rotating inside the cylindrical body of the valve, controlling the flow of fluid.
Spool valves are utilized in hydraulic systems of construction machinery such as excavators and bulldozers, controlling the direction and pressure of hydraulic fluids. They are also used in industrial machinery, air pressure systems in manufacturing lines, hydraulic controls in automobiles like brakes and transmissions, and for controlling the flow of liquids or gases in chemical plants and manufacturing facilities.
