If the main housing or board is intact, repair is usually the better option. We can restore most units to working condition with tested parts.

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.

  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

Diagnostic Testing

NC Servo Technology operates thirteen in-house test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using a range of hydraulic fluids like Skydrol and MIL-5606. Our pre-shipment testing verifies spec-level operation.
