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.</p> <strong>Is this LFA 40 WEA-71/ compatible with other series, like the 6X?</strong><br> <p>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.</p> <strong>What is the nominal size (NG) of this component?</strong><br> <p>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.</p> </p> <p><em>Last Update: Friday, March 13, 2026</em></p> <p><em>spareparts2day is not an authorized distributor, reseller or representative of the products featured on this website.
