How We Rebuild This Valve

We disassemble every valve, inspect it inside and out, and clean all moving parts. Components that fail inspection are swapped out before the valve is rebuilt and tested.

  • 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.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.

Testing and Bench Verification

NC Servo operates over a dozen dedicated flow 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 performance testing verifies spec-level operation.
