Why Repair With NC Servo

NC Servo specializes in both valves and electronic controls, which lets us operate without the delays of OEM service centers.

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.

  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Leak and Performance Testing

Each YASKAWA 28 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our operational testing verifies consistent performance.

Performance Data

Every YASKAWA 28 we service is tested under real-world conditions. Our diagnostics verify performance against published specifications. Specification sheets and Cycle life data are available for purchase upon request.
