A fluid control component allows flow in one of two distinct configurations. It features three ports that can be connected in different combinations depending on the current state. For instance, in one position, a pressure source might be connected to an output while the third port is blocked. When shifted to the second position, the pressure source could be blocked, and the output connected to exhaust. This type of valve is commonly employed in pneumatic or hydraulic systems to direct pressurized fluid to various actuators or control elements.
These components are critical for automating various processes and simplifying complex fluidic circuits. Their use contributes to increased efficiency, precision, and safety in many applications. Historically, such valves represent a significant advancement over manual control methods, enabling remote operation and integration with automated control systems. The compact design and reliable operation of these valves make them an integral part of modern engineering.
