Repair Process

Once a valve arrives, we tear it down fully, examine key surfaces, and replace worn or damaged parts using components we stock in-house, cutting out OEM lead times.

  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.
  • 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.

Hydraulic Testing Process

Each MOOG D633Z570B 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.
