This depends on the maximum Inrush current of the valve drive and the operating current of the valve drive.

The maximum inrush current of the VAA/S is 300 mA for 2 min at Ts up to 60 °C per output.

Ts is the surrounding temperature.

The maximum operating current of the VAA/S is 160 mA at TS up to 45 °C per output.
