Independent Repair Facility
We stock common wear parts in-house, so most rebuilds don’t require outside sourcing. Less waiting, faster turnaround.
Disassembly and Rebuild Procedure
We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.
- Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
- 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.
- Teardown: Every valve is disassembled for internal inspection.
Leak and Performance Testing
NC Servo operates thirteen in-house 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.
