After changing an ISO standard VS7-6-FG-S-1* to a VQ7-6-FG-S-1*, the valve no longer turns OFF. The solenoid valve is driven by TRIAC output. What are the possible causes of this?

The apparent power of the ISO standard VQ7-6/VQ7-8 series valve has been reduced compared with that of the VS7-6/VS7-8 and VP7-6/7-8 series.
Therefore, the allowable leakage voltage of the AC type is now 12.5% or less of the rated voltage (compared with 20% or less of the rated voltage for the VS7/VP7).

Can an IS10M pressure switch of an AC30C-03DG-S-A be set to 0.4 to 0.45 MPa?

For AC-A/AC-B series modular F.R.L units with a white body, the pressure switch must be replaced with an IS10M-□-6-A pressure switch (set pressure: 0.1 to 0.6 MPa).
Note 1) For new AC series units, an IS10M-□-6-A pressure switch with a spacer is required.
