Bürkert 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, enabling 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 also possible. 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.

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.
• 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

Circuit function	Description
C (CF C)	3/2-way solenoid valve, servo-controlled, normally closed
C (CF C)	2 × 3/2-way solenoid valve, servo-controlled, normally closed
D (CF D)	2 × 3/2-way solenoid valve, servo-controlled, normally open
H (CF H)	5/2-way solenoid valve, servo-controlled. Pressure applied via port (1), therefore one of the two ports (2) or (4) is under pressure.
L (CF L)	5/3-way solenoid valve, in middle position all ports locked
M (CF M)	5/3-way solenoid valve, in middle position ports 2 and 4 ventilated
N (CF N)	5/3-way solenoid valve, in middle position ports 2 and 4 exhausted
Z (CF Z)	5/2-way solenoid valve, impulse variant with 2 coils

SIA Variant (for safety-related shut-off)

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. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Approvals and Conformities

• Explosion protection: As a category 3 device suitable for zone 2/22. ATEX: II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc. IECEx: Ex ec IIC Gc / Ex tc IIIC Dc.
• North America: UL Listed for the USA and Canada (UL 61010-1). UL Recognized for Hazardous Locations (Class I, Zone 2; Class II, Zone 22; Class I, Div 2).

Explosion Protection Safety Notes

• In a current explosive atmosphere, the 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 is prohibited in a current explosive atmosphere unless it is ensured by suitable test equipment that no explosive atmosphere is present.
