Rebuild Steps

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

  • 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.
  • 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.

Testing and Bench Verification

NC Servo Technology operates over a dozen dedicated flow test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using industry-standard fluids including MIL-5606 and Skydrol. Our pre-shipment testing verifies spec-level operation.
