BURKERT Type 8652 AirLINE valve island has been especially developed for process automation requirements. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller. This, therefore, enables a fast overview of the plant status. The hardware is optimised for installation at the bottom of the control cabinet. Installation on a standard rail is, of course, also possible. Moreover, key pneumatic functions ensure increased process reliability. For instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks.

• Safety-related shut-off of valves possible
• Higher plant availability with PROFINET S2 (system redundancy)
• Process reliability through pneumatic functions
• Optimised for installation at the bottom of the control cabinet
• EX-variants: ATEX / IECEx Zone 2, CCC, cURus HazLoc CL I, II, III Div 2

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• This makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Valves Type 6534 for Safety-Related Shut-off, SIA Variant (optional)

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. Manual override is not required for these valve variants. Technical data of Type 6534 valves, SIA variant correspond to standard device data. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Safety Instructions for Potentially Explosive Areas

Danger from electrical voltage

• Before intervening in the device or system, switch off the power supply and secure it against being switched on again.
• In an existing explosive atmosphere, connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.
• The use of the Hot Swap function in an existing explosive atmosphere is prohibited.
