What is a Spool Valve?
Overview
This video explains what a Spool Valve is and how it is used in hydraulic and pneumatic systems.
A spool valve is a type of directional control valve that uses a cylindrical spool inside a housing to control fluid or air flow.
By moving the spool back and forth, the valve can open, close, or redirect flow between different ports, allowing precise control of actuators like cylinders and motors.
Spool valves are widely used because they can control multiple flow paths and switching operations efficiently in industrial systems.
