In a pneumatic control system, the nozzle typically receives a regulated air supply pressure of approximately:

In a pneumatic control system, the nozzle typically receives a regulated air supply pressure of about 140 kPa. This pressure level is common for effective operation, ensuring that the system can adequately move air and perform control functions without causing damage to components or resulting in overly aggressive airflows.

The choice of 140 kPa aligns well with standard practices in pneumatic systems, where the pressure is substantial enough to generate the necessary force for actuators or other devices downstream, while still being safe and manageable within the system's design limits. This regulated pressure helps in maintaining the precision of the control mechanisms, allowing for consistent performance in automation processes.

While other pressure options, such as 210 kPa or 140 psi, represent higher pressures, they may not be ideal for typical pneumatic control applications, which often require a balance between sufficient force and maintaining component safety. Conversely, a much lower pressure like 20 kPa would likely be insufficient for most pneumatic applications, leading to inadequate system functionality.
