The Burkert Type 8647 AirLINE SP pneumatic valve island is a modular, electropneumatic automation system consisting of connection and valve modules. It has been especially developed for safe and complete integration into the decentralised peripheral systems "SIMATIC ET 200SP" and "SIMATIC ET 200SP HA" from Siemens. Pneumatically operated process valves, pneumatic cylinders, or other pneumatic components can be connected to the pneumatic outputs. If the pneumatic components are installed with position feedbacks, the position of the actuated pneumatic components can be displayed on the associated pilot valve, saving time on start-up and maintenance.

Combining modules from the distributed Siemens I/O systems with the valve block AirLINE SP Type 8647 provides an integrated system of electronic and pneumatic components. The valve block and the electronic modules provide numerous features, including extensive configuration options, diagnostics capabilities, and safety-related shut-off functions.

Solenoid Pilot Valves

Type 6524 and Type 6525

The pilot valve Type 6524 (single and double valve) and Type 6525 (single valve) consist of a pilot flipper solenoid valve Type 6144 and a pneumatic seat valve. The circuit function allows switching of high pressures with low power consumption and short switching times. The pilot valves are equipped with a manual override as standard.

Type 0460

The solenoid valve Type 0460 consists of a pneumatic valve body fitted with a double coil pilot valve. The principle allows switching of high pressures together with low power consumption and fast switching times. All valves are equipped with manual override as a standard.

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• This makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Note

The valves of Type 0460 cannot be installed with AirLINE Quick due to their size.

Circuit Functions

Symbol	Description
C (CF C)	3/2-way solenoid valve. Servo-controlled, with manual override. Normally closed.
C (CF C)	2 × 3/2-way solenoid valve. Servo-controlled, with manual override. Normally closed.
D (CF D)	3/2-way solenoid valve. Servo-controlled, with manual override. Normally open.
H (CF H)	5/2-way solenoid valve. Servo-controlled, with manual override. Pressure applied via port (1), therefore one of the two ports (2) or (4) is under pressure.
L (CF L)	5/3-way solenoid valve. With manual override. In middle position all ports locked.
N (CF N)	5/3-way solenoid valve. With manual override. In middle position ports 2 and 4 exhausted.
Z (CF Z)	5/2-way solenoid valve. Impulse variant with 2 coils and manual override. Pressure applied via port (1), therefore one of the two ports (2) or (4) is under pressure.

Approvals and Conformities

• Explosion protection: Optional ATEX / IECEx (BVS 18 ATEX E 078 XII 3G Ex ec IIC T4 Gc / IEC Ex BVS 18.0068 X Ex ec IIC T4 Gc). As a category 3 device suitable for zone 2.
• North America (USA/Canada): Optional UL Listed for the USA and Canada according to UL 61010-1 and CAN/CSA-C22.2 No. 61010-1.

Safety-related Applications

The electrical shutdown of valve Types 6524 and 6525 causes them to return to the rest position. The selection of the appropriate circuit function of the valve (CFC, CFD or CFH) depends on the application and is the responsibility of the user. To avoid brief back pressures in the event of a safety shutdown, the use of valve blocks with integrated check valves is strongly recommended.
