Rebuild Steps

Every MOOG PSI9-3 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.
  • 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.

Testing and Bench Verification

Each MOOG PSI9-3 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our functional testing verifies proper functionality.
