LFA32D19-7X/ Logic Cover R900923087

The Bosch Rexroth LFA32D19-7X/ logic cover, material number R900923087, is a control cover for 2-way cartridge valve hydraulic systems. Bosch Rexroth official product information identifies this item as LOGIC COVER LFA32D19-7X/. It belongs to the Rexroth LC/LFA cartridge valve product family, which is used to build compact hydraulic directional functions in manifold blocks and high-flow hydraulic control systems.

The complete product identification must always be kept together for accurate procurement and replacement: LFA32D19-7X/ / R900923087. In hydraulic spare-parts purchasing, the model code and material number are both important. The material number confirms the Bosch Rexroth item, while the full model code confirms the hydraulic function, nominal size, component series and configuration. Short descriptions such as “LFA32 cover” or “Rexroth logic cover” are not enough for safe replacement.

According to Bosch Rexroth RA 21010 technical data, LC and LFA components are used for 2-way cartridge valves and control covers for directional functions. The product family covers sizes 16 to 160, component series 2X, 6X and 7X, with series-level data listing maximum operating pressure of 420 bar and maximum flow up to 25000 L/min. These are general product-family values, and the final operating conditions for the LFA32D19-7X/ logic cover should always be checked according to the cartridge valve, manifold design, pilot circuit and machine documentation.

The model code LFA32D19-7X/ contains important configuration information. The LFA section identifies a Bosch Rexroth control cover for 2-way cartridge valves. The 32 section indicates nominal size 32. The D19 section identifies the D19 function or symbol version and should be checked against the hydraulic schematic before replacement. The 7X section indicates component series 70 to 79, with unchanged installation and connection dimensions within the same series range. The final slash should be copied exactly when matching the model code.

This Bosch Rexroth LFA32D19-7X/ logic cover R900923087 is used together with a matching LC cartridge valve element in a hydraulic block. In this type of system, the cartridge valve forms the main hydraulic power section, while the LFA control cover closes the cartridge cavity and provides the required control function. This modular structure allows high-flow directional control functions to be built into compact manifolds, which is common in heavy industrial hydraulic systems.

In operation, a 2-way cartridge valve system is controlled through the working ports and spring chamber. The control cover plays an important role in how the cartridge valve opens, closes or responds to pilot oil. Because the logic cover is part of a complete hydraulic circuit, its function cannot be judged by appearance alone. The correct replacement depends on the full model code, cartridge valve type, hydraulic symbol, pilot oil path, manifold drilling and machine control requirements.

The LFA32D19-7X/ logic cover is commonly relevant for hydraulic presses, forming machines, steel equipment, die-casting machines, heavy industrial machinery, hydraulic power units and production lines using LC/LFA cartridge valve technology. These systems often require reliable high-flow directional control, compact block design and serviceable modular valve construction. When replacing the cover, the existing hydraulic block, cartridge valve, connected pilot lines and original spare-parts list should all be reviewed.

For procurement teams and maintenance engineers, the key purchasing reference is the full Bosch Rexroth model LFA32D19-7X/ together with material number R900923087. Similar Rexroth LFA covers may differ in nominal size, D symbol version, component series, pilot connection, nozzle configuration, seal material or special suffix. Even a small difference in the model code can change the hydraulic behavior or installation compatibility.

Before ordering the Bosch Rexroth LFA32D19-7X/ logic cover R900923087, buyers should compare the nameplate, hydraulic schematic, manifold drawing and original machine spare-parts list. If the part is already installed, photos of the logic cover, cartridge valve assembly, manifold block and connected pilot lines can help confirm the correct configuration. If the matching LC cartridge valve is also required, its model and material number should be checked separately.
