The highly versatile valve island was developed for use in the food & beverage, pharmaceuticals and cosmetics industries, as well as in water treatment systems. To save space it can be mounted in the control cabinet together with different Siemens modules for controlling up to 64 valve functions. The valves are directly connected to the Siemens I/O system. This enables fast and seamless integration both at the time of commissioning and later, during monitoring of operation. The display of the number of switching cycles allows optimal preventive maintenance of the system to minimise wear and downtimes. Maximum system availability is achieved by means of the pneumatic valves in the supply channel: they are hot swap capable, so they can be replaced during operation. Further information and the options available on this system can be seen here.
Built in Monitoring
The Type 8647 AirLINE SP valve island features pressure sensors and an LCD, which displays detailed status information such as the position of the pilot and process valves directly at the device – both by means of icons and plain text. This enables fast detection and elimination of faults. The use of ring topology and the Media Redundancy Protocol (MRP) ensures continued operation of the system in the event that a communication client fails. This increases system availability and ensures the reliability of the customer’s process.
Mixing of Media is Impossible
Like all Bürkert valve islands, the Type 8647 has a crucial safety function: check valves in the exhaust duct. They ensure that pilot valves and actuators operate reliably, by preventing pressures peaks. This eliminates the possibility of any mixing of different media.

Example application: drinking water supply
In waterworks, all steps in the water treatment process, such a fi ltration and ion exchange, are generally executed as separate automated processes. A separate control cabinet with a valve island that controls the connected actuators is therefore required for each step in the treatment process. This is necessitated by the stringent requirements for reliable operation of the overall plant (100% redundancy), in order to guarantee the continuous availability of high-quality drinking water. Plant availability is also important in case of maintenance procedures or
unforeseeable incidents such as natural disasters or malfunctions in other waterworks.
Example application: process water for hygienic applications
Automation of actuators for process water in the pharmaceutical and food & beverage industries is achieved either by one large, central control cabinet or by smaller control cabinets distributed throughout the plant. The new valve island type 8647 is used in both automation methods. With the integrated safety function, automation tasks can be
implemented in a fail-safe manner.
In standard central automation the valve islands are remote from the actual process. The advantages of this are fast and easy maintenance, since all control units are accessible at a single location. In distributed automation the control cabinets, along with the valve islands, are more compact and are located very near to the process. This improves the response time of the connected valves and reduces the expenses for cables and installation.
Treated process water is used for cleaning processes in the production of medications, foods and beverages, for example, or it can also be an ingredient in medications and foods.
