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.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Hydraulic Testing Process

NC Servo Tech operates over a dozen dedicated flow test stands, 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 pre-shipment testing verifies consistent performance.
