Frequently Asked Questions

Restoration Workflow

Each valve goes through a full teardown to expose wear and buildup. After cleaning every surface, we replace damaged parts and reassemble the unit to spec.

• Final Performance Verification: After reassembly, each valve is bench-tested to ensure it meets or exceeds original performance specifications.
• Thorough Decontamination: Every component is put through a deep cleaning process to remove grime and buildup.
• Rigorous Testing: The reassembled unit undergoes rigorous leak and pressure testing to verify it performs to specification.
• In-House Parts Sourcing: Many repairs use reliable components sourced from our extensive inventory of existing units.

Testing & Diagnostics

NC Servo Technology operates thirteen state-of-the-art test stands, including specialized setups specifically designed for proportional and servo valves. Every valve goes through comprehensive performance and leak testing using a range of hydraulic fluids like Skydrol and MIL-5606. Our operational testing ensures consistent performance.
