Spool Valve

A spool valve, also known as a poppet valve, is a type of valve that controls the flow of fluid by adjusting an opening and closing mechanism in its design. It consists of a cylindrical spool that moves within a fixed housing to open or close off the flow of fluid. The movement of the spool is controlled by an external force such as pressure, which determines the amount of flow allowed through the valve. Spool valves are commonly used in hydraulic and pneumatic systems for precise control of fluid flow.
