Repair Process

Every MOOG D662-709 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.
  • 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.

Diagnostic Testing

Each MOOG D662-709 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our performance testing verifies spec-level operation.
