LC32A40E7X/-004 Logic Cartridge Valve R900924564

The Bosch Rexroth LC32A40E7X/-004 logic cartridge valve, material number R900924564, is a 2-way cartridge valve for hydraulic directional functions. It belongs to the Bosch Rexroth LC cartridge valve range, which is used together with suitable LFA control covers to build compact hydraulic control circuits. The complete product identification should always be kept together for purchasing and replacement: LC32A40E7X/-004 / R900924564.

According to Bosch Rexroth RE 21010 technical data, the LC and LFA series covers 2-way cartridge valves and control covers for directional functions. The series includes sizes 16 to 160, component series 2X, 6X and 7X, with a maximum operating pressure of 420 bar and maximum flow up to 25000 L/min for the overall product family. These values are series-level data and should be checked against the final machine configuration, control cover and operating conditions before installation.

The full model code LC32A40E7X/-004 contains important configuration details. The LC section identifies the cartridge valve without control cover. The 32 section identifies nominal size 32. The A code identifies an area ratio of 2:1, with the annulus area equal to 50% of the seat area. The 40 code identifies the cracking pressure version. The E code identifies a valve poppet without damping nose. The 7X code identifies component series 70 to 79, with unchanged installation and connection dimensions within the same series range. The absence of a V seal code indicates the standard NBR seal version in the Rexroth type code.

The LC32A40E7X/-004 logic cartridge valve is used as part of a modular hydraulic control system. In a typical cartridge valve arrangement, the valve element is installed into a standardized cavity and controlled through a matching cover or pilot circuit. This makes the LC series suitable for compact block systems where high flow capacity, low leakage and flexible hydraulic control functions are required. The correct function depends not only on the cartridge valve, but also on the selected control cover, pilot oil supply and hydraulic circuit design.

In operation, 2-way cartridge valves are hydraulically controlled through the working ports and the spring chamber. The effective opening and closing areas, together with the spring force and pilot pressure, determine the spool or poppet position. Bosch Rexroth technical information states that LC cartridge valves can be flowed through from A to B or from B to A. When the closing area is pressurized by pilot oil, channel A can be blocked leak-tight. This operating principle allows LC cartridge valves to be integrated into directional control, load-holding and high-flow hydraulic circuits.

The complete model LC32A40E7X/-004 must not be shortened during procurement. Similar Bosch Rexroth LC cartridge valves may differ in size, area ratio, cracking pressure, damping nose design, seal material, component series or special suffix. The -004 suffix should be copied exactly from the valve nameplate or original spare-parts list, because suffix changes can indicate a special configuration or customer-specific variant. For this reason, buyers should always use both the full model and the material number R900924564 when requesting a quotation.

This valve is commonly relevant for hydraulic power units, presses, heavy industrial machinery, steel equipment, forming machines and other hydraulic systems using cartridge valve blocks. Before ordering the Bosch Rexroth LC32A40E7X/-004 logic cartridge valve R900924564, maintenance engineers should compare the valve nameplate, manifold drawing, hydraulic schematic and original spare-parts list. It is also important to confirm whether the existing system requires only the LC cartridge valve or also a matching LFA control cover.

For international buyers, accurate identification reduces the risk of ordering a similar but non-matching cartridge valve. Please provide the full model code, material number, required quantity, destination country and preferred delivery term when sending an inquiry. If the valve is installed in an existing manifold, clear photos of the nameplate, cartridge valve, control cover and hydraulic block can help confirm the correct configuration.
