The control devices used in pneumatics are called __________.

In pneumatic systems, control devices play a critical role in directing and regulating the flow of compressed air to various components. Valves are the key elements responsible for this function. They control the air flow by opening, closing, or adjusting the passage of air, allowing for precise movement and operation of other pneumatic devices such as cylinders. By controlling the airflow, valves can determine the speed, direction, and force of the pneumatic components they are connected to.

Compressors, while essential in providing the compressed air needed for pneumatic applications, do not control the air flow within the system. Cylinders are actuators that convert the pneumatic pressure into mechanical motion but do not manage or regulate that pressure. Filters are important for maintaining the quality of the air supplied to the system by removing contaminants but do not act as control devices for directing or regulating airflow. Therefore, the correct identification of valves as the control devices in pneumatics emphasizes their essential function in the effective operation of pneumatic systems.
