Pneumatic Spool Valves

Pneumatic spool valves are valves that use a spool to control the flow of air or other gases. They are commonly used in pneumatic systems to control the flow of air to various components. The spool is a cylindrical piece of metal that is moved by a solenoid or other actuator. The spool is designed to move in a linear fashion, allowing it to open and close ports in the valve body. This allows the user to control the flow of air to the various components in the system.
