Rebuild Steps
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.
- Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
- Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
- Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
Hydraulic Testing Process
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 performance testing verifies consistent performance.
