BURKERT 341006 (Type 8652 AirLINE) is a preconfigured 24-slot modular pneumatic valve island developed for process automation systems. Each of the 24 valve slots is fitted with a Type 6534 servo-controlled 5/2-way monostable pneumatic valve (Circuit Function H / CF-H). The island is equipped with an AirLINE Quick adapter plate manufactured from stainless steel 1.4301 (304), providing direct floor or wall mounting into control cabinets while routing pneumatic tubing outside the enclosure.

Pneumatic process connections feature push-in fittings constructed from stainless steel 1.4401: D10 mm for main supply port 1 (P) and exhaust, and D6 mm for working ports 2 and 4. Process safety is provided through integrated check valves in exhaust ducts 3 (R) and 5 (S) to suppress pressure peaks, alongside an integrated pneumatic HotSwap function on port 1 (P) allowing replacement of single valves while adjacent stations remain fully pressurized. Communication is managed by an integrated ME43 fieldbus gateway supporting multi-protocol Industrial Ethernet over dual RJ45 connectors, supplemented by 48 integrated digital inputs across six electronic modules.

Pneumatic Circuit Functions and Solenoid Valves

Article 341006 is fully loaded with 24 individual Type 6534 valves operating under Circuit Function H (5/2-way monostable, servo-assisted). When pressure is applied via port 1, either port 2 or port 4 is pressurized. Manual override is equipped as latching and spring-return.

Safety Shutdown Options (SIA Variants)

For applications requiring safety shutdown independent of fieldbus communication, Type 6534 SIA valves (such as CF-H article 338805) incorporate coded plug-in terminals for potential-free contacts. Opening the circuit interrupts valve actuation without bus master intervention.

Electrical Connections and Industrial Ethernet Interface

Type 8652 uses physically separated power supply circuits for communications/electronics and pneumatic coils to protect communication lines from switching transients.
