BURKERT Type 8647 AirLINE SP 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. This can save time on start-up and maintenance.

System Integration

The valve block AirLINE SP Type 8647 allows direct connection to the I/O systems SIMATIC ET 200SP and SIMATIC ET 200SP HA. It offers easy diagnostics via an LC display and enables safety-related shut-off of valves.

System Overview

Combining modules from the distributed Siemens I/O systems SIMATIC ET 200SP/SP HA with the valve block AirLINE SP Type 8647 provides an integrated system of electronic and pneumatic components. Depending on the requirement, electrical and pneumatic modules with various functions can be combined with each other.

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.

Circuit Functions

Circuit function	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).
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.

Safety-related shut-off

The electrical shutdown of valve Types 6524 and 6525 causes them to return to the rest position. To avoid brief back pressures in the event of a safety shutdown, the use of valve blocks with integrated check valves is strongly recommended.
