BURKERT Type 8640 modular valve island (SKU 20050149) is designed to solve diverse and complex control problems through its systematic modular construction and combination of pneumatic and electrical interfaces. This REV3 variant features an 11 mm width per station, a 4-bank configuration with 4x (2x 3/2) valve functions, and a collective socket module. Bodies and connection modules are made of high-quality polyamide and are assembled using built-in snap connectors.

Key Features

• Compact design with 11 mm width per station.
• Modular configuration allowing up to 24 valve slots.
• Simple exchange of valves with integrated check valves in ports 3 (R) and 5 (S).
• Pneumatic HotSwap capability in port 1 (P).
• Collective connection module with looped-through ground potential and screw-type terminals.

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.

WARNING

Risk of injury due to electric shock. Switch off voltage before working on the device or system. Secure against reactivation.

Pneumatic Installation

• Check the hose lines for contamination and clean them before connection.
• If necessary, install dirt traps upstream of the valve inlet (≤ 5 µm).
• 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.

TIP

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.

Electrical Installation

• When screwing in the solenoid with the cable plug, make sure that the seal is properly seated.
• Always connect the protective conductor and check electrical continuity between coil and housing to prevent electric shock.
• The correct polarity is a prerequisite to ensuring that the device functions. Note the label on the surface of the coil. Pulse duration at least 50 ms.
