Pneumatic control valves, also known as directional control valves, are devices used to regulate and control the flow of air and other inert gases within pneumatic systems. These valves are categorized based on several factors, including the number of inlet and output ports, the type of actuator used (manual, mechanical, electromagnetic, or pneumatic), the valve’s status when deactivated (normally open or normally closed), and the number of flow paths or switching positions.
These categorizations assist in determining the appropriate valve for specific applications and operational requirements, ensuring optimal performance in various pneumatic systems. Pneumatic control valves play a crucial role in controlling the movement and operation of pneumatic actuators, contributing to the efficiency and effectiveness of industrial processes that rely on compressed air or gas.
