BURKERT 20141447 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, up to 24 valve functionalities may be realized on one valve unit. This specific configuration features a 16.5 mm width per station, a collective socket module, and is designed for DIN-rail installation.

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

Installation

Standard rail installation

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

WARNING

Risk of injury due to unintentional activation of the system and uncontrolled restart. Secure the system against unintentional activation. Following installation, ensure a controlled restart.
