BOSCH REXROTH 4WRKE 25 E350L-3X/6EG24ETK31/A1D3WC15M

This valve is indeed produced by Bosch Rexroth Pneumatics, a division of German industrial giant Robert Bosch GmbH.

The format of the part number follows the structure used by Rexroth, with each section representing specific information about the component:

• The first three characters (in this case "4W") indicate the type and purpose of the valve. In this example, it is a directional control valve (not a proportional or servo valve).
• Following that are two digits indicating the size and power of the valve. Here, "25" represents a nominal width of 200 mm (though this can vary depending on the exact model).
• Next comes another set of three letters, in this case "E35", which indicates the maximum operating pressure of the valve. In this instance, it means the valve is designed to operate at pressures up to 350 bar.
• Then there are more letters and numbers, "-3X/-6EG24ETK31". These appear to relate specifically to different variations or options available for the valve. It's difficult to determine their exact meaning without further information from Rexroth.
• Finally, we have "A1D3WC15M". This appears to refer to additional features or options for the valve such as magnetic valves, solenoids, hydraulic pumps etc. Further details would need to be provided by Rexroth.

Overall, the part number provides some basic information about the function and parameters of the valve but more detail would be needed to fully identify the component and ensure compatibility with your system.
