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 to corrosion
– Resistance to acid and alkaline cleaning agents
– Complies with relevant protection classes (see Appendix A
“Technical data”).
– Low maintenance
– Pre-assembled valves
– Wired solenoid coils
– Central air supply
– Centrally ducted exhaust air
– Inspected unit
– Extension/conversion possible at a later stage
