Disassembly and Rebuild Procedure

Every MOOG J664-112B 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.
  • 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.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.

Leak and Performance Testing

We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing. Our test facility supports performance logging and report generation. Our pre-shipment testing verifies spec-level operation.
