Directional control valves are essential components in hydraulic and pneumatic systems, designed to regulate the flow direction of fluids or gases. These valves feature multiple ports and pathways, enabling precise control over actuator movements in industrial machinery. Common types include spool, poppet, and rotary valves, with configurations like 2-way, 3-way, or 4-way. They are widely used in manufacturing, automation, and mobile equipment applications for tasks requiring sequenced operations or safety interlocks. Key specifications include flow capacity, pressure rating, actuation method (manual, solenoid, pilot), and materials compatible with various media.
