1.3.1 In-line valve manifolds

Festo P.BE-CDVI-EN en 1202e
There are two types of in-line manifold blocks on the CDVI:
– The manifold block has 4 or 8 valve positions. Each CDVI
consists of at the most one manifold block, i. e. no further
manifold blocks can be used for additional valve posi-
tions.
– The expansion blocks (2-valve or 1-valve expansion block)
are available in four different versions:
– Standard version without power supply
– Version with pneumatic supply connection
– In addition, on the CDVI with fieldbus connection:
– Version with electrical power supply
– Version with pneumatic supply connection and
electrical power supply
Both versions provide 1 or 2 valve positions. A maximum of
8 Mo-expansion blocks or 4 Bi-expansion blocks can be
mounted to one manifold block. Mixed components are per-
missible.
Valves and blanking plates are fitted on the in-line valve mani-
folds. The working lines (2) and (4) are provided for each
valve position on the in-line valve manifolds. Each valve posi-
tion supports triggering 2 solenoid valves (only applies to
manifold blocks, otherwise depends on expansion). The end
plates form the termination. The in-line valve manifolds pro-
vide the following connections:
– Common channels for supply and exhaust air for:
– Compressed air supply to the valves
– Removal of the exhaust and pilot exhaust air at the
valves.
– Electric signals from all solenoid coils.
