How We Repair Your Unit

Each REXROTH 4WRKE10E50-21/6A24FZ9/D3MR-443 undergoes reconditioning — disassembly, parts replacement, reassembly, and bench testing before shipment.

Experience and Warranty

NC Servo operates independently, so we’re not tied to manufacturer delays or restrictions. That means more flexibility when your system is down.

Frequently Asked Questions

Yes. Send us photos of the unit from multiple angles. Our team has serviced thousands of models and can often ID them visually.

In most cases, repair costs less than replacement, especially for legacy or OEM-specific models. We evaluate every unit and let you know what makes sense.

We confirm next steps with you if a unit can’t be rebuilt. No work proceeds without your approval.

Inspection and root-cause analysis are part of our standard process. We identify the issue before starting any repair work.

Send the unit in whatever condition it’s in. We clean everything during teardown before inspection begins.

Disassembly and Rebuild Procedure

Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Teardown: Every valve is disassembled for internal inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

Testing and Bench Verification

With thirteen in-house test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our functional testing verifies proper functionality.
