Repair Process

We rebuild every valve from the inside out: cleaning, inspection, parts replacement, reassembly, and bench testing.

  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Testing and Bench Verification

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 performance testing verifies spec-level operation.

Repair, Rebuild and Exchange Options

Beyond standard sales, we offer specialized overhauls for your MOOG 771K602 unit. Our teardown process includes mineral bath cleaning and internal inspection, using only replacement replacement components.
