Disassembly and Rebuild Procedure

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.

  • 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.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

NC Servo Tech operates thirteen in-house test stands, including setups for proportional and servo valves. Every valve goes through performance and leak testing using standard test fluids to match your operational needs. Our pre-shipment testing verifies consistent performance.
