Bosch Rexroth LFA25D-7X/F is a size 25 control cover for a hydraulic logic cartridge, factory article R900905302. It is sold as an individual cover, not as a complete insert-and-cover valve assembly. The D execution provides an external pilot connection at port X; it has no stroke limiter.
The /F code identifies the remote control port, not FKM seal material. The standard seal execution is NBR. The pilot connection in the applicable drawing is G 1/4. The cover must be matched to the selected cartridge, manifold cavity and intended pilot circuit; no arbitrary insert pairing is assigned.
Installation dimensions and control details use the manufacturer’s March 2005 series document. Complete-circuit limits depend on all attached components. The manufacturer illustration is a representative D-cover drawing; the full dimensional sheet remains necessary for installation.
