Which component is used to regulate air flow in a pneumatic circuit?

The flow control valve is a crucial component in a pneumatic circuit specifically designed to regulate air flow. Its primary function is to manage the speed at which air enters or exits a cylinder, thereby controlling the motion of actuators. By adjusting the flow of air, the flow control valve enables precise control over the operation of pneumatic devices, ensuring that they operate at the desired speed and efficiency.

The flow control valve achieves this by providing a mechanism to restrict or allow the flow of air based on the specific requirements of the system, often incorporating adjustable or fixed orifices to fine-tune flow rates. This regulation is essential in applications where speed and timing are critical for performance, such as in automated processes or machinery that relies on pneumatic actuation.

In contrast, the other components mentioned serve different purposes. A pneumatic cylinder is mainly for converting air pressure into mechanical motion. A pressure switch monitors the air pressure within the system but does not regulate flow. A connector is used to join different components in the circuit but does not directly affect airflow regulation.
