Rebuild Steps

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • Final Performance Verification: After reassembly, each valve is bench-tested against original performance specifications.
  • Ultrasonic Cleaning: All parts go through ultrasonic cleaning to remove contaminants before 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 factory specs.

Testing and Bench Verification

NC Servo operates our 13-stand test facility, 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 functional testing verifies spec-level operation.

Stock Availability

With more than 17,000 valve units in inventory, we can often provide faster turnaround by sourcing parts in-house rather than waiting on OEM lead times.
