Rebuild Steps

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • 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.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.

Testing and Bench Verification

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our operational testing verifies proper functionality.

Technical Specifications

Every MOOG D662Z1917C we service is tested under operating environments. Our diagnostics verify performance against published specifications. Specification sheets and Cycle life data are available for purchase upon request.

Maintenance Tips

  • Replace inline filters according to maintenance schedules to maintain proper flow rates.
  • Schedule preventive maintenance intervals based on duty cycle, not just calendar time.
  • Document all maintenance activities to track performance trends over time.
