I would like to confirm whether I’m reading the “Flow Rate Characteristics” graphs in the VBA series catalog correctly. For the VBA40A, when P1 = 0.5 MPa, 0.6 MPa outlet air flows constantly at 1500 L/min (ANR). Is this correct?

The VBA40A “Flow Rate Characteristics” graphs show us that air flows constantly at 1500 L/min (ANR) from the outlet when the inlet pressure (P1) is 0.5 MPa and the outlet pressure is 0.6 MPa. And the set pressure of the VBA series booster regulator at this time is 1 MPa when the outlet air flow rate is 0 L.
This means that when air is not consumed on the outlet side, the outlet pressure becomes 1 MPa.
If 0.6 MPa air is constantly consumed at 1500 L/min (ANR) on the outlet side, the booster regulator will run continuously with almost no stopping time, resulting in a reduced service life.
