BURKERT 20066295 Type 8640 modular valve island 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 for this specific model is achieved by a multi-pole interface. Bodies and connection modules are made of high-quality plastic (polyamide) and are easy to assemble by means of the built-in snap connectors.

Key Features

• Compact design and modular configuration
• Higher flexibility in control cabinet due to AirLINE Quick
• Simple exchange of valves (with option "P-shut-off" – also possible during operation)

Installation and Safety

DANGER!

Risk of injury due to high pressure and escaping medium.

• Switch off the pressure before working on the device or system. Vent or drain the pipes.

Risk of injury due to electric shock.

• Switch off voltage before working on the device or system. Secure against reactivation.
• Observe any applicable accident prevention and safety regulations for electrical devices.

Installation Notes

• Prior to installation: Clean the pipes. If necessary, attach dirt trap upstream. Do not use the coil as a lever when screwing in the connections.
• Pneumatic connection: Push the hose lines into the push-in connections of the solenoid valves until they come to a stop. Use PTFE tape or elastomer seal for sealing the threaded connection.
• Electrical connection: Screw on the cable plug observing the maximum tightening torque of 0.3 Nm. Check that the seal is correctly fitted.
