If the supply pressure of your CPV valve terminal lies between
3...8 bar, you can operate the terminal with internally
branched auxiliary pilot air. In this case the auxiliary pilot air
will be taken from connection 1 in the right-hand end plate.
If the CPA valve terminal with internal pilot air is used, the
centre connection must be fitted with a blind plug (see dia-
gram).
