BURKERT Type 8640 modular valve island system is designed to solve diverse and complex control problems due to its systematic modular construction and combination of pneumatic and electrical interfaces. By putting together a row of pneumatic modules with different numbers of valves, 2 to 24 valve functionalities may be realized on one valve unit. Electrical connectivity is achieved by either fieldbus interfaces, common connection (parallel connection technique) or multipin interfaces. The valves allow different applications to be covered. Bodies and connection modules are made of high-quality plastic (polyamide) and are easy to assemble by means of the built-in snap connectors.

Compatible Solenoid Valves

Type 6524 and Type 6525

• The pilot valves 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.

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.

Type 6526 and Type 6527

• The solenoid valve Type 6526 and Type 6527 consist of a pneumatic valve body fitted with a Type 6106 rocker solenoid valve.

Type 5470

• The solenoid valve Type 5470 consist of a pneumatic valve body fitted with Type 6106 rocker pilot valve. An armature with a tilting bearing, similar or a rocker, tilts within the body of the pilot valve, and switches the valve.
• Type 5470 R is available as a 3/2 and 4/2-way valve.

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.

Note

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

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

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.

Installation Guidelines

WARNING

Risk of injury from quickly accelerating device parts and unconnected compressed air hoses flapping around. ▶ Before applying pressure to the valve, check all hose connections and fittings for tight, secure fit.

Tightening torques for port connections

Observe the following tightening torques when screwing into the port connections. The specified tightening torque may vary depending on the sealing system.

Port size	Marking/function	Recommended tightening torque [Nm]	Maximum tightening torque [Nm]
G1/4, NPT1/4	P, R/S connection	4...7	20
G1/8, NPT1/8	P, R/S connection A/B valve outlets	3...6	7

Recommended action for push-in connectors

Our push-in connectors meet the requirements specified in the ISO 14743:2020 standard. Ensure that the appropriate combination of hose material (polyamide or polyurethane) and push-in connector is used, as different materials require different holding forces. Press the hose into the push-in connector with sufficient force. The hose must be inserted deep enough into the push-in connector so that it is held correctly by the claws.
