What is the main function of a restrictor in a pneumatic system?

The main function of a restrictor in a pneumatic system is to control the rate of airflow. By providing a controlled pathway for air to flow through, the restrictor helps to regulate the speed and pressure of the air entering different components of the system. This is crucial in applications where precise control of motion or pressure is needed, such as in actuators or flow controls.

Unlike components that increase pressure, filter contaminants, or store compressed air, a restrictor is specifically designed to limit the flow rate, making it essential for maintaining optimal performance and preventing damage to the system from excessive airflow. This regulation helps to ensure that the entire pneumatic system operates smoothly and efficiently.
