AirLINE is more than a valve island. It accepts a wide array of digital and analogue field inputs and sends digital and analogue outputs for exact control where it matters.

This unique device marries virtually any combination of valve island functionality and electronic signals to the widest range of fieldbus connectivity.

AirLINE leaves the freedom to choose between electronic modules as it creates a fully integrated fieldbus communication, process valve actuation and control platform.
