Please consider switching to a product from the VBA20A/40A series.
Further details on discontinued products can be found here.

In addition, when the inlet pressure of the VBA20A is 0.5 MPa, the set pressure of the regulator must be 1.0 MPa in order to obtain an outlet pressure of 0.8 MPa at 600 L/min.
If no air is consumed on the outlet side, the outlet pressure rises to 1.0 MPa, so be sure to check the withstand voltage of the peripheral equipment.

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.
