Which pilot port does each LVA, LVC, and LVD series N.O., N.C., and double acting valve use?

The N.C. type uses the PA port and the N.O. type uses the PB port to switch. Do not block the other pilot port because it is used as a breathing hole.
As for the double acting type, it is switched by the ON/OFF of both the PA and PB ports.
