PN16
BURKERT 20132441 Type 8652 AirLINE is a 16-slot electropneumatic valve island pre-configured for automated process environments. The unit integrates 15 dual 3/2-way normally closed solenoid valve slices (Circuit Function C) and 1 blind plate on an anodised aluminium AirLINE Quick base plate. Pneumatic connections comprise push-in D10 mm brass fittings for main supply port 1 and push-in D6 mm brass fittings for working ports 2 and 4. Operating under an internal auxiliary pilot air supply from 3 bar to 10 bar, the system handles process pressures from vacuum (-1.00 bar) up to 10.00 bar across an operating temperature range of -10 °C to +55 °C.
Communication is managed via an integrated ME43 fieldbus gateway executing multi-protocol Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic) through dual RJ45 Ethernet ports (X1 and X2). The valve island is built in the Basic variant without an integrated LC display or digital input modules. It incorporates a pneumatic intermediate feed module to maintain uniform pilot and main line pressure along the 16-slot rail.

Pneumatic Configuration and Valve Functions
Article 20132441 is populated with 15 valve slices of Circuit Function C (CF C) and 1 blind plate slice. Each CF C slice contains two independent 3/2-way servo-assisted solenoid valves that remain closed in the unpowered state (normally closed). Actuation is supported by manual overrides with latching detents. Unused slot 16 is fitted with a Type 6534 blind plate to preserve manifold pressure containment.
| Station | Hardware Component | Circuit Function | Function Description |
|---|---|---|---|
| Positions 1–15 | Type 6534 Solenoid Valve | 2x 3/2-way CF C | Servo-assisted, normally closed, unpowered closed, latching manual override |
| Position 16 | Type 6534 Blind Plate | Dummy position | Isolates pneumatic channels; allows future valve retrofitting |
Pilot Air Routing
Article 20132441 utilizes internal auxiliary pilot air. The pilot supply branches internally from main supply port 1. The main line pressure must remain at or above 3 bar (up to 10 bar) to ensure reliable servo switching of the pilot stages.
AirLINE Quick Bottom-Mounted Adapter Plate
The valve island is factory-fitted with an AirLINE Quick adapter plate manufactured from anodised aluminium. This interface mounts directly into a cutout in the floor or wall of the control cabinet, placing pneumatic push-in fittings on the cabinet exterior.
