It depends on the unit and scope of work. We provide an estimated timeline after initial evaluation.

We regularly work on units with missing labels. Send us a few images and any visible part numbers, and we can usually match it.

Why Repair With NC Servo

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

Factory-level test stands dedicated to UNKNOWN COIL performance verification

Repair Process

Every UNKNOWN COIL gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Diagnostic Testing

With over a dozen dedicated flow 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 performance testing verifies spec-level operation.

Parts and Inventory

With over 17,000 valves in stock, we can often provide faster turnaround by sourcing parts in-house rather than waiting on OEM lead times.

Maintenance Tips

  • Perform fluid analysis to detect contamination early and prevent system damage.
  • Schedule preventive maintenance intervals based on duty cycle, not just calendar time.
  • Flush the hydraulic system after any major repair to remove debris before reinstalling the UNKNOWN COIL.
