1.1 Overview of variants
Festo assists you in solving your automation tasks at machine
level with CPA valve terminals. The modular structure of the
CPA valve terminal for the CP system enables you to use the
CPA valve terminals optimally in your machine or system.
Due to its compact structure the CPA valve terminal can be
mounted close to the actuators to be actuated. Short com-
pressed air tubing can therefore be used. System losses can
therefore be minimized and the times required for pressuriz-
ing and exhausting the tubing can be minimized. This enables
very compact valves with high flow rate to be used, therefore
helping to reduce costs.
CPA valve terminal
with CPX terminal
This CPA valve terminal is available with 2 to max. 22 single-
coil valve locations or up to max. 11 double-coil valve loca-
tions. Maximum 22 valve coils can be actuated.
