1. Summary of components Overview of the CPV-SC valve terminal Festo assists you in solving your automation task at the machine level with valve terminals. Due to their compact design, the CPV-SC valve terminals can be fitted close to the actuators to be controlled. This enables short compressed air tubing to be used.
