Repair Process

Every MOOG 30-389A gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Teardown: Every valve is disassembled for internal inspection.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Hydraulic Testing Process

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 operational testing verifies consistent performance.

Repair, Rebuild and Exchange Options

Beyond standard refurbishment, we offer specialized overhauls for your MOOG 30-389A unit. Our disassembly process includes bench testing and pressure testing, using only new replacement components.
