Repair Process

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

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

Hydraulic Testing Process

NC Servo 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 functional testing verifies proper functionality.
