What are the operating pressure and temperature limits for the Burkert Type 8652 AirLINE valve island?

The valve island operates within a pressure range of Vac to 10 bar and an ambient temperature range of -10 °C to +55 °C. If utilizing external supply air for the auxiliary pilot, the required pressure is 3 to 10 bar.

What is the flow rate of the Burkert 8652, and how does the Hot Swap feature affect it?

The standard flow rate QNn value for air is 310 l/min, measured at +20 °C with 6 bar pressure at the valve inlet and a 1 bar differential pressure. Utilizing the Hot Swap feature reduces this flow rate by approximately 3%.

How many valve slots and functions can the Burkert Type 8652 accommodate?

The Type 8652 can accommodate a maximum of 24 valve slots and up to 48 maximum valve functions. Variants configured with 16, 20, and 24 valve slots also support an optional pneumatic intermediate supply.

What are the pneumatic connection sizes when using the AirLINE Quick adapter?

The AirLINE Quick adapter uses push-in D 10 mm (3/8") connections for pneumatic supply and exhaust, and push-in D 6 mm (1/4") connections for the working ports. The adapter plate itself is constructed from either stainless steel 1.4301 or anodised aluminium.

What hazardous area approvals are available for the Burkert 8652 EX-variants?

The EX-variants are approved as category 3 devices suitable for zone 2/22, carrying ATEX (BVS 20 ATEX E 031 U) and IECEx (IECEx BVS 20.0024 U) certifications. Additional optional approvals include CCC for China and UL Recognized for Hazardous Locations (Class I, Div 2 / Zone 2).

What type of operating medium is required for the 8652 valve island?

The required operating medium is oil-free or lubricated compressed dry air, or neutral gases. The compressed air quality must meet the ISO 8573-1: 2010, Class 7.4.4 standard, and a 5 μm filter is recommended.

What are the electrical power requirements for each valve on the 8652 island?

Each valve requires a 24 V DC operating voltage and has a nominal power of 0.7 W with a 29 mA nominal current. After power reduction is applied, the consumption drops to 0.175 W and 10 mA per valve.

BURKERT 20109612 8652 AirLINE Valve Island

Burkert Type 8652 AirLINE valve island has been especially developed for process automation requirements. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller, enabling a fast overview of the plant status.

The hardware is optimised for installation at the bottom of the control cabinet. Installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability. For instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks.

Product Design and Assembly

Electronic Module with Digital Inputs (Optional)

The digital inputs are supplied (24 V) by the electronic module. Current is limited to maximum 30 mA per digital input. Standard 3-wire sensors and 2-wire sensors with voltages between 10…30 V as well as mechanical limit switches can be used.

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. Manual override is not required for these valve variants. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Module-Based Safety Shutdown (Optional)

Optional connections for module-based safety shutdown: Terminal 1 = valve unit 1, Terminal 2 = valve unit 2, etc. To use the switch-off function, connect the connection to a potential-free contact.
