The AirLINE Type 8562 (photo) is a new valve island for control cabinets. Type 8652 was designed for applications in the water-treatment, pharmaceutical, cosmetics and food-and-beverage industries. It offers user-adjustable, integrated monitoring and diagnostic functions that improve system availability and process reliability, while also enabling preventive maintenance. An integrated display shows detailed onsite information, such as the current-switching statuses of the pilot and process valve, and issues a message if pre-set pressure-limit values are exceeded. The valve island is significantly smaller than its predecessor, says the manufacturer, and therefore fits into compact control cabinets that can be placed close to process valves. The valve island communicates via common industrial Ethernet protocols or Profibus DP. Each valve can be replaced during live operation without shutting down the system. As an additional safety function, check valves are used in the exhaust channel to prevent the unwanted activation of valves by pressure peaks and the resulting mixing of media. This also provides reliability on the pneumatic side. — Bürkert Fluid Control Systems, Ingelfingen, Germany
