Overview

We’ve serviced hundreds of Proportion Air CB2E080 units over the years. Each one goes through the same controlled teardown, parts replacement, and testing process.

About Our Shop

NC Servo operates independently, so we’re not tied to manufacturer delays or restrictions. That means more flexibility when your system is down.

How We Rebuild This Valve

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.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • 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.

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 industry-standard fluids including MIL-5606 and Skydrol. Our performance testing verifies consistent performance.
