Bürkert AirLINE SP Electropneumatic Automation System

The AirLINE system represents a universal interface between process and system control. It integrates electric and pneumatic building blocks into an assembly, enabling a modular and flexible structure of fieldbus modules, pilot valves and I/O modules thanks to simple locking technology on the standard rail.
