Repair Process

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

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Hydraulic Testing Process

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 consistent performance.
