Pneumatic control valves come in various types, each designed for specific applications. Ball valves, butterfly valves, and solenoid valves are prevalent in pneumatic systems. Ball valves provide quick shut-off capabilities, while butterfly valves offer a more compact and lightweight solution for regulating flow. Solenoid valves, on the other hand, use electromagnetic coils to control flow, allowing for precise on-off switching in applications where automated control is required.
