Rebuild Steps

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.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Teardown: Every valve is disassembled for internal inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.

Hydraulic Testing Process

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 a range of hydraulic fluids like Skydrol and MIL-5606. Our pre-shipment testing verifies consistent performance.
