In a pneumatic system, what is the function of a control valve?

The function of a control valve in a pneumatic system is primarily to act as a path for the air to flow towards the actuating unit. This component is crucial as it directs the compressed air to various parts of the system, influencing how and when the actuating unit operates. By opening or closing the valve, the system can control which areas receive air, enabling functionality such as movement, positioning, and operation of tools.

While maintaining air pressure, regulating flow rate, and controlling temperature are essential aspects of pneumatic systems, they do not directly describe the primary role of a control valve. Rather, these functions are typically managed by other components in the system such as pressure regulators or flow control valves, which complement the operation of the control valve by ensuring that the air delivered is at the appropriate levels for optimal functioning.
