How is flow control typically achieved in a pneumatic circuit?

Flow control in a pneumatic circuit is typically achieved using flow control valves. These valves are specifically designed to regulate the velocity of air flowing through a pneumatic system, allowing for precise control over the speed of actuators such as cylinders and motors. By adjusting the flow rate, these valves can help synchronize movements and ensure efficient operation of the equipment.

While adjusting the size of pneumatic cylinders may impact the force they exert or the volume of air they require, it does not directly regulate the flow of air in the system. Manipulating pressure gauges provides information about the system's pressure rather than controlling flow. Changing air compressor settings affects the overall pressure and flow rate available to the system but does not provide the fine-tuning necessary for effective flow control within specific circuits.

Using flow control valves thus facilitates the necessary adjustments to air flow, enhancing control over pneumatic operations and improving the performance of the system overall.
