BURKERT 20135147 is a pre-configured 24-station execution of the Type 8652 AirLINE valve island platform, built for process automation enclosures. This unit integrates sixteen 5/2-way monostable pilot valves (Circuit Function H) at positions 1 through 16 and eight blanking plates at positions 17 through 24. It combines an anodized aluminium AirLINE Quick base plate, an integrated pneumatic intermediate feed module, 48 digital input channels distributed across six 8DI electronic modules, and a dual-port Industrial Ethernet interface (RJ45).

Process safety features include integrated check valves inside exhaust channels 3 (R) and 5 (S) to isolate unvented pressure spikes from back-actuating adjacent actuators. Channel 1 (P) features pneumatic HotSwap isolation, enabling single-valve replacement while main air pressure remains applied to the manifold without disrupting adjacent active channels.

AirLINE Quick Control Cabinet Mounting

The AirLINE Quick adapter interface attaches directly into cutouts at the base or wall of the control cabinet. All primary air feed lines and cylinder working ports pass directly through the cabinet floor, eliminating bulkhead connectors and cabinet-internal tubing harness routing.

Valve Configuration and Circuit Functions

Article 20135147 houses 16 active Type 6534 pilot solenoid valves and 8 blanking dummy plates, occupying the 24 available station slots.

Slot Allocation	Installed Component	Circuit Function	Nominal Diameter	Switching Time (Open / Close)
Slots 1–16	Type 6534 Solenoid Valve	CF-H (5/2-way monostable, servo-controlled, manual override)	4 mm	20 ms / 25 ms
Slots 17–24	Dummy Valve Plate	Blind closure for future expansion	—	—

CF-H Operation: Pressure applied at supply port 1 channels pilot air to energize the spool, directing pressure to working port 2 or working port 4 depending on coil excitation state.

Cabinet Installation and Hot Swap Requirements

When mounting the island inside a control cabinet, clearance dimensions to enclosure walls and door front edges must be respected to operate the Hot Swap locking levers.

Hot Swap Operation Rule

During pneumatic Hot Swap, individual Type 6534 pilot valves can be unfastened and lifted from their station under line pressure up to 10 bar. Ensure the locking screws are backed out evenly and replacement units are aligned on the locating pins before torquing.
