Pneumatic Directional Control Valve

A pneumatic directional control valve is a type of valve used to control the direction of air flow in a pneumatic system. It is typically used to control the direction of a cylinder or other pneumatic actuator. The valve is usually operated by a lever, knob, or other manual control, but can also be operated automatically by a solenoid or other electrical device. The valve is typically composed of a body, a spool, and a seal. The body is the housing for the valve, and the spool is the part that moves to control the flow of air. The seal is used to prevent air from leaking out of the valve.
