What is the pneumatic pressure range in PSI?

Pneumatic systems in aircraft are designed to function within a relatively small, controlled pressure window. The operating range is about 12 to 20 psi. This range provides enough pressure to reliably drive air-powered actuators and valves while staying within the limits that the system’s hoses, fittings, and relief devices are built to tolerate. If the pressure drops below roughly 12 psi, actuators may not operate properly; if it climbs above about 20 psi, the system is at risk of overpressure and triggering relief or causing component stress. So 12–20 psi is the safe, effective range for the pneumatic portion of the aircraft’s systems.
