Compatibility and replacement
Order with the 10-character material number R900481623; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code Z2FS6-2-4X/1QV on the nameplate should match exactly.
The values in the table come from the official Bosch Rexroth product data. If your old part shows a different series index (for example 5X instead of 6X), send us a photo and we will confirm the current equivalent.
