Rebuild Steps
Each valve goes through teardown to expose wear and buildup. After mineral bath cleaning, we replace damaged parts and reassemble the unit to spec.
- Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
- Teardown: Every valve is disassembled for internal inspection.
- Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
- Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
Diagnostic Testing
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 operational testing verifies consistent performance.
