BURKERT 20048272 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. Moreover, 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
• Makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Property	Description
AirLINE Quick Adapter Plate	Stainless steel 1.4301 or Anodised aluminium
Pneumatic connection	Stainless steel 1.4401 or Nickel-plated brass
Pneumatic Supply / Exhaust	Push-in D 10 mm, 3/8"
Pneumatic working ports	Push-in D 6 mm, 1/4"

Circuit Functions

The Type 8652 supports various standard circuit functions including 3/2-way and 5/2-way solenoid valves (Circuit functions C, D, H, L, M, N, Z). It also supports SIA variants for safety-related shut-off.

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: Optional ATEX / IECEx (II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc) suitable for zone 2/22.
• North America: Optional UL Listed and UL Recognized for Hazardous Locations (Class I, Zone 2 / Class II, Zone 22 / Class I, II, III, Division 2).
• China Compulsory Certification (CCC): Optional for hazardous applications in China.

Explosion Protection Safety Notes

When using the device in a potentially explosive area, ensure the control cabinet is approved for use in hazardous areas and provides at least IP54 protection (for 3G/Gc) or IP64 (for 3D/Dc). Do not use the Hot Swap function in a present explosive atmosphere unless it is ensured that no explosive atmosphere is present.
