BURKERT 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, enabling a fast overview of the plant status. The hardware is optimised for installation at the bottom of the control cabinet, though installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts that prevent unplanned actuation due to pressure peaks.

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

Circuit Functions

The Type 8652 supports various standard circuit functions via the Type 6534 replacement valves:

• Circuit function C (CF C): 3/2-way solenoid valve, servo-controlled, normally closed.
• Circuit function D (CF D): 2 × 3/2-way solenoid valve, servo-controlled, normally open.
• Circuit function H (CF H): 5/2-way solenoid valve, servo-controlled.
• Circuit function L (CF L): 5/3-way solenoid valve, in middle position all ports locked.
• Circuit function M (CF M): 5/3-way solenoid valve, in middle position ports 2 and 4 ventilated.
• Circuit function N (CF N): 5/3-way solenoid valve, in middle position ports 2 and 4 exhausted.
• Circuit function Z (CF Z): 5/2-way solenoid valve, impulse variant with 2 coils.

SIA Variant

SIA variants are available for safety-related shut-off. These valves are equipped with additional connection terminals, allowing a valve circuit to be interrupted by an external switch.

Product Installation

Hot Swap in Explosion Hazard Areas

The use of the Hot Swap function is prohibited in a present explosive atmosphere. If it can be proven and ensured by means of suitable test equipment that there is no explosive atmosphere for a certain period of time, it is permissible to remove/insert valves using Hot Swap during this period.

To use the Hot Swap function, always observe a minimum distance to the front edge of the control cabinet when installing the valve island inside the control cabinet.

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.
