Disassembly and Rebuild Procedure
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.
- In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
- Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
- 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.
Leak and Performance Testing
NC Servo Technology 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 operational testing verifies consistent performance.
