Build, test, and debug regular expressions
Parses Bosch Rexroth Z1S6 series order codes for subplate-mounted, direct-operated hydraulic pressure valves (e.g., Z1S6P05-4X/V). Named groups capture mounting type, unit size, port function (A, B, P, T, AB-P, B-A, T-P, etc.), cracking pressure in bar (05/15/30/50), series 4X, and seal material (NBR, FKM, MT), plus optional surface coating, pipe port, and special version (SO68/SO90/SO104) suffixes. Useful for validating and extracting specifications from industrial valve part numbers.
