Independent Repair Facility

We stock common wear parts in-house, so most rebuilds don’t require outside sourcing. Less waiting, faster turnaround.

How We Rebuild This Valve

Every MOOG 76-509A gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Hydraulic Testing Process

NC Servo Technology operates our 13-stand test facility, 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 proper functionality.
