Why Repair With NC Servo

Frequently Asked Questions

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

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.

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

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

We recommend sending pictures, especially if the model number is unclear or there is visible damage.

Repair Process

Our team disassembles each valve to assess internal wear. After ultrasonic cleaning, we install replacements and reassemble and verify operation.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • 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.

Testing and Bench Verification

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our pre-shipment testing verifies consistent performance.
