BURKERT 20128182 (Type 8652 AirLINE) is an electro-pneumatic 16-valve-slot valve island developed for process automation applications. Configured with a PROFIBUS DPV1 fieldbus interface via a 9-pin Sub-D connection, article 20128182 integrates five 3/2-way Circuit Function C (normally closed) solenoid valves on positions 1 through 5, while positions 6 through 16 are sealed with blind plates. The mechanical base utilizes an anodised aluminium AirLINE Quick adapter plate designed for bottom or wall cutout mounting in control cabinets, routing all pneumatic connections directly through the cabinet wall. Process connections feature brass push-in fittings with D10 mm for main air supply and D6 mm for working ports.

Type 8652 AirLINE incorporates an integrated LC display providing status and diagnostic readouts in plain text and symbols. To safeguard process continuity, the island includes integrated check valves in exhaust ducts 3 (R) and 5 (S) to prevent unintended actuator movement caused by backpressure spikes, as well as a pneumatic HotSwap mechanism on supply duct 1 (P) enabling online valve replacement under pressure with an approximate flow reduction of only 3%.

AirLINE Quick Mounting and Cabinet Installation

AirLINE Quick enables the valve island to mount directly onto the floor or wall of a control cabinet. This direct interface eliminates internal bulkhead fittings and cabinet-internal pneumatic piping, allowing users to reduce cabinet volume and installation assembly time.

Feature	Technical Specification
Adapter Plate Material	Stainless steel 1.4301 or anodised aluminium (Article 20128182: Aluminium)
Pneumatic Fittings Material	Stainless steel 1.4401 or nickel-plated brass (Article 20128182: Brass)
Valve Function Capacity	8, 16, 24, 32, 40, and 48 valve functions
Supply / Exhaust Ports	Push-in D10 mm, 3/8"
Working Ports	Push-in D6 mm, 1/4"
Permissible Mounting Positions	Control cabinet floor, control cabinet wall

When installing the valve island inside the control cabinet, clearance dimensions to the cabinet front edge and rear wall must be maintained to ensure proper insertion and removal when utilizing the HotSwap function.

INFO

HotSwap operation allows single pneumatic valves to be dismounted and replaced while the remaining valve slots maintain system pressure. When active, flow rate QNn is reduced by approximately 3% through the HotSwap non-return mechanism.

Dimensions and Structural Layout

Type 8652 valve islands feature an 11 mm grid per station. Article 20128182 represents the 16-valve-slot version equipped with an intermediate supply module.
