Disassembly and Rebuild Procedure

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

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Teardown: Every valve is disassembled for internal inspection.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

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 pre-shipment testing verifies proper functionality.
