Disassembly and Rebuild Procedure

Each valve goes through a full teardown to expose wear and buildup. After cleaning every surface, we replace damaged parts and reassemble the unit to spec.

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets factory specs.
  • Full Teardown: Every valve is fully disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Ultrasonic Cleaning: All parts go through ultrasonic cleaning to remove contaminants before inspection.

Diagnostic Testing

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 consistent performance.
