  • Time for draining and line cooling

Increase productivity

Size Blinding Deblinding More production
1/2”~ 14” 1 to 4 hours 1 to 4 hours 2 to 8 hours
16”~ 48” 4 to 12 hours 4 to 12 hours 8 to 24 hours
  • Time saving for and draining and line cooling are not included
  • Less pre-purge time
  • Immediate work after stopping line

Saving cost for maintenance

  • No consumable parts except gaskets
  • No tools, wedges, crane, bolts are necessary
  • Quick and Positive action in emergency
  • Prevent vaccum losing
  • Prevent contamination by mixing
  • Prevent leaking accident in service
  • Prevent environmental pollution
