Seal Stability Logic

The pop-up valve is the heart of pot pressurization. Even a 5% seal leak causes a technical pressure drop at the nozzle, leading to irregular surface profiles and increased abrasive consumption. Moisture in the air line accelerates seal rot; always verify your **Moisture Separator** performance before shift start.

Inspection Intervals

  • Daily: Visual check for seal leaks
  • Weekly: Clean gasket & seat ring
  • Monthly: Measure gasket hardness
