How We Rebuild This Valve

Every MOOG 761-4088B gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Final Performance Verification: After reassembly, each valve is bench-tested against published performance specifications.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Diagnostic Testing

With our 13-stand test facility and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our functional testing verifies spec-level operation.
