BURKERT 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 is achieved by either fieldbus interfaces, common connection (parallel connection technique) or multipin interfaces. The bodies and connection modules are made of high-quality plastic (polyamide) and are easy to assemble by means of built-in snap connectors.

Key Features

• Compact design
• 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

WARNING

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.

Valve Block Installation

Standard rail installation:

1. Hook the valve block with the upper groove into the standard rail (35 x 15 or 35 x 7.5 EN 50022).
2. Snap the lower clamping pieces into the standard rail.
3. Tighten the screws on the clamping pieces.

Wall installation: Fasten the valve block directly to the wall with M4 screws.

Electrical Installation

Screw on the cable plug observing the maximum tightening torque of 0.3 Nm. Check that the seal is correctly fitted. Connect the protective conductor and check electrical continuity between coil and housing to prevent electric shock.
