Bürkert AirLINE Type 8652 and 8653 valve islands

The Bürkert AirLINE (Type 8652) and AirLINE Field (Type 8653) valve islands are designed for applications in the pharmaceutical, cosmetics and food and beverage industries as well as for water treatment applications. They offer users adjustable monitoring and diagnostic functions that improve system availability and process reliability, while at the same time enabling preventive maintenance.

An integrated display shows detailed on-site information such as the current switching statuses of the pilot and process valves, issues a message if preset pressure limit values are exceeded and displays errors such as cable breaks in plain text. During development, particular attention was also devoted to the compact design. The valve island 8652 is smaller than its predecessor and therefore fits into compact control cabinets that can be placed close to the process valves.

The valve island communicates via common industrial Ethernet protocols or Profibus DP. In sealed ring topologies and Profinet I/O communication, the Media Redundancy Protocol (MRP) for highly available networks ensures that even a switch or cable break can be compensated for.

Each valve is hot-swap capable, which means it can be replaced during live operation without shutting down the system. As an additional safety function, check valves are used in the exhaust channel. These prevent the unwanted activation of valves by pressure peaks and the resulting mixing of media. Consequently, stable operation is also ensured on the pneumatic side.
