FAQ

What is the function of an LFA logic cover in a hydraulic system?

An LFA logic cover is part of a two-way cartridge valve assembly. It contains the pilot control orifices and passages that determine the function of the main valve, in this case, acting as a pilot-operated check valve.

Compatibility between different series (e.g., 7X vs. 6X) is generally high for mounting patterns. However, it is crucial to consult the official Rexroth datasheet to verify any differences in pressure ratings, flow characteristics, or pilot ratios.

The nominal size is NG40, as indicated by the "40" in the model number. This refers to the size of the cavity it is designed to fit, corresponding to a nominal port diameter of 40 mm.
