Repair Process

Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.

  • Teardown: Every valve is disassembled for internal inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

NC Servo Tech operates our 13-stand test facility, 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 operational testing verifies consistent performance.
