Modern valve island enhances process reliability

24 November 2017

The Bürkert AirLINE Type 8652 valve island for control cabinets incorporates integrated monitoring and diagnostic functions designed to improve process reliability.

The compact Type 8652 was designed for applications in the pharmaceutical, cosmetics, food and beverage industries as well as for water treatment applications. 

It offers adjustable monitoring and diagnostic functions that are said to 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 and will issue a message if pre-set pressure limit values are exceeded or will display errors, such as cable breaks, in plain text. 

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

Every 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.
