Question: 1 / 400

In a pneumatic system, what is the role of a valve?

To store air

To control the flow of air

In a pneumatic system, the primary role of a valve is to control the flow of air. Valves regulate the direction, pressure, and volume of air moving through the system. They can open to allow air to flow freely, close to stop the flow, or redirect the flow to different components as needed. By controlling these aspects, valves are crucial for the operation of pneumatic devices, allowing them to function efficiently and perform specific tasks, such as moving actuators or powering tools.

Devices that store air, such as tanks or reservoirs, fulfill a different function and are not classified as valves. Compressors are specifically designed to increase the pressure of air, while expanding air typically refers to processes involving energy conversion or pneumatic actuation rather than the function of a valve. Therefore, recognizing the essential role of the valve in managing airflow is key to understanding pneumatic system operations.
