BURKERT 20132960 Type 8640 is a modular valve island for pneumatics, specifically configured as a 33mm 5-bank valve block. The Type 8640 valve unit 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, multiple valve functionalities may be realized on one valve unit.

Bodies and connection modules are made of high-quality plastic (polyamide) and are easy to assemble by means of the built-in snap connectors.

Features

• Compact design
• Modular configuration
• Higher flexibility in control cabinet due to AirLINE Quick
• Simple exchange of valves
