Disassembly and Rebuild Procedure

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Teardown: Every valve is disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

Each REXROTH 4WRTE-43-M-00 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our performance testing verifies proper functionality.

Maintenance Tips

  • Conduct thorough visual inspections for wear or leaks during routine maintenance.
  • Document all maintenance activities to track performance trends over time.
  • Check valve alignment carefully to prevent undue stress on internal components.
