LR25DB10E1X/ Logic Cartridge Valve 1818509301

The Bosch Rexroth LR25DB10E1X/ logic cartridge valve, material number 1818509301, is a hydraulic cartridge valve used in compact hydraulic control blocks and manifold systems. Public product references identify this item as LR25DB10E1X/ with Bosch Rexroth material number 1818509301. For accurate procurement and replacement, the complete model and material number should always be used together: LR25DB10E1X/ / 1818509301.

The LR25DB10E1X/ logic cartridge valve should be selected by exact model code, not by appearance only. Bosch Rexroth logic cartridge valves and 2-way cartridge valve elements are commonly installed inside hydraulic manifolds, where the external shape may look similar but the internal hydraulic function can be different. A small change in the model code may affect nominal size, area ratio, cracking pressure, damping design, seal material, spring chamber control or special execution.

According to Bosch Rexroth official technical information for 2-way cartridge valves, cartridge valves are hydraulically controlled through the two working ports A and B and the spring chamber. This means the final valve function depends not only on the cartridge element itself, but also on the manifold, control cover, pilot oil path and hydraulic circuit design. The Bosch Rexroth LR25DB10E1X/ logic cartridge valve 1818509301 should therefore be checked against the machine hydraulic schematic and original spare-parts list before ordering.

The model code LR25DB10E1X/ contains important identification information. The LR section identifies the Bosch Rexroth logic cartridge valve family. The 25 section indicates the nominal size reference used in the Rexroth ordering code. The DB10 section identifies the hydraulic configuration and should be copied exactly from the original nameplate or parts list. The E1X section indicates the component series or execution version, and the final slash is part of the model format. Because Rexroth logic elements can have very similar model strings, the full code should remain visible in all purchasing documents.

Logic cartridge valves are widely used in hydraulic systems that require high-flow control in a compact manifold design. Depending on the circuit arrangement, a cartridge valve element can be used for directional functions, pressure functions, load holding, unloading, bypassing or controlled opening and closing of hydraulic flow paths. The actual function of LR25DB10E1X/ depends on the installed manifold and pilot circuit, so buyers should not assume interchangeability based only on the LR25 series name.

The Bosch Rexroth LR25DB10E1X/ logic cartridge valve 1818509301 may be relevant for hydraulic presses, machine tools, industrial power units, forming machines, steel equipment, production machinery, test systems and other hydraulic equipment using cartridge valve technology. These systems often use compact block designs where cartridge valves provide strong flow capacity while saving space compared with large external valve assemblies.

For maintenance engineers, the most important replacement reference is the complete Bosch Rexroth model LR25DB10E1X/ and material number 1818509301. Short descriptions such as “LR25 valve,” “Rexroth logic valve” or “cartridge valve” are not enough for accurate replacement. Similar Rexroth LR valves may differ in size, cracking pressure, damping version, area ratio, spring arrangement or special suffix. If the valve is part of a larger cartridge valve assembly, the matching control cover or manifold drawing should also be reviewed.

Before ordering the LR25DB10E1X/ logic cartridge valve, buyers should compare the valve body marking, hydraulic schematic, manifold cavity, control cover and original machine spare-parts list. If the old part is installed inside a hydraulic block, photos of the stamped model code, cartridge cavity, control cover and full manifold assembly can help confirm whether the requested item matches the existing system. If a preset value, certificate, country-of-origin document or special packaging requirement is needed, this should be stated during quotation.

This product page is prepared for international buyers who need a clear purchasing reference for Bosch Rexroth material number 1818509301. Because detailed public official specifications for this exact Store item are limited, this page keeps the product identification accurate and avoids unsupported pressure, flow or dimensional claims. The safest purchasing method is to provide the exact model LR25DB10E1X/, material number 1818509301, required quantity and machine reference.
