1.1 The Clean Design valve terminal (CDVI) from Festo
The CDVI from Festo is a valve terminal especially for the
splash range in the food and packing industry. It offers the
following advantages:
 easy to clean (larger spaces between the valves, no sharp
edges, no narrow radii, no dirty corners)
 increased resistance against corrosion
 resistance to acid and alkaline cleaning agents
 complies with relevant protection classes (see appendix A
Technical specifications")
 low maintenance
 valves already fitted
 valve solenoid coils already wired
 central air supply
 central ducted exhaust
 device tested
 extension/conversion possible at a later stage.

1.3.1 Sub−bases
There are two types of sub−bases on the CDVI:
 Base block with 4 or 8 valve locations Each CDVI consists
of maximum one base block, i.e. no further base blocks
can be used for additional valve locations.
 There are two variants of the extension blocks: the stan
dard design without supply connections and a type with
supply connections. Both types provide 2 valve locations.
Maximum 2 extension blocks can be mounted on a base
block.
Valves and cover plates are fitted on the sub−bases. Work
connections 2 and 4 are provided for each valve location on
the sub−bases. Two valve solenoid coils can be controlled per
valve location. The end plates form the termination. The sub−
bases provide the following:
 Common channels for supply and exhaust air:
 compressed air supply to the valves
 removal of the exhaust and pilot air at the valves.
 The electric signals from all valve solenoid coils

Note:
In the case of the CDVI with 3 pressure zones,
the supply extension block may only be used in
conjunction with a standard extension block.
The supply extension block must be fitted
between the base block and the standard
extension block.
