If the pressure of a single VBA series booster regulator cannot be increased up to the set pressure due to the pressure increase ratio, can 2 VBA40As be used in series?

Please consider using the VBA43A type.
If 2 booster regulators of the same size are installed in series, the supply flow rate to the second VBA may be insufficient, and the pressure may not be increased to the required level.
If the use of 2 booster regulators in series is desired, assuming that the outlet flow rate will be 1/2 and 1/2, check whether a VBA40A followed by a VBA20A can be used.
