BURKERT 20074343 (Type 8652 AirLINE) is a modular electro-pneumatic automation valve island engineered to control pneumatic actuators and process valves in industrial automation systems. Configured with a 24-bank base and a stainless steel AirLINE Quick (ALQ VA) adapter plate, this unit provides 48 discrete pneumatic control functions using 24 individual 2x 3/2-way CF-C (normally closed) valve slices. Each pneumatic pilot station incorporates Burkert Type 6164 pilot solenoid valves acting on Type 6534 pneumatic spool valves.

Pneumatic Configuration and Process Connections

The 24-slot manifold incorporates stainless steel push-in fittings for harsh operating environments, featuring D10 supply connections and D6 working ports. Exhaust ports 3 (R) and 5 (S) integrate non-return check valves to prevent backpressure infiltration into inactive lines.

Hazardous Area Approvals and Identification Plates

BURKERT Type 8652 valve islands operating in potentially explosive atmospheres are certified under ATEX Directive 2014/34/EU, IECEx, and China Compulsory Certification (CCC via SITIIAS according to GB/T 3836.2021). The unit holds component type examination certificates BVS 20 ATEX E 031 U and IECEx BVS 20.0024 U issued by DEKRA Testing and Certification GmbH (Bochum), with PTB surveillance (CE0102).

Valve islands deployed in hazardous locations carry two nameplates: a general device nameplate and a dedicated explosion-protection label.

Enclosure and Thermal Ratings

Inside a control cabinet at a maximum ambient temperature of +55 °C, the assembly complies with temperature class T4 limits. When utilizing the AirLINE Quick interface mounted to the control cabinet base, the maximum exterior operating surface temperature does not exceed 80 °C.

Installation Rules and Operational Safety

Hazardous Area Installation Constraints

• Enclosure Protection: Install Type 8652 in an enclosure certified for hazardous areas meeting EN/IEC 60079-0 and EN/IEC 60079-7 (minimum IP54 for category 3G/Gc) or EN/IEC 60079-31 (minimum IP6X for category 3D/tc).
• Pollution Degree: The system must operate exclusively in micro-environments meeting pollution degree 2 or better according to IEC 60664-1.
• Overvoltage Protection: Transient suppression must prevent peak supply voltage from exceeding 140% of the nominal 24 V DC supply interface rating.
• De-energized Handling: In explosive atmospheres, terminal connections (24 V DC power, SIA, EVS, digital inputs) and fixed cables must only be connected or disconnected in a completely de-energized state. Hot-swap replacement of valves is prohibited in explosive atmospheres unless an approved testing procedure confirms the atmosphere is completely non-hazardous.

An auxiliary label stating WARNING DO NOT CONNECT OR DISCONNECT WHEN ENERGIZED is supplied with the valve island. Affix this label in a prominent position on the unit whenever cabinet installation limits visibility of the primary explosion protection nameplate.
