Steriflow SVC Up-Flow Series Sanitary Check Valves

Two-piece, spring-less sanitary disc check valve for vertical up-flow for bioprocess media and purified water applications for the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries:

  • WFI loop, pump out: vertical line up-flow, downstream of pump
  • WFI loop, standby pump - validation: vertical line up-flow, downstream of standby pump with precision bleed for back flow of hot WFI bleed
  • Media/Buffer Prep: back flow prevention during dilution or pump out
  • Bioreactor: vessel bottom inlet sparge line back flow prevention
  • Process vessel: over pressure and vacuum protection upstream of vent filter
  • F & B and consumer H & B process inputs, outputs, purified water and clean utility back flow prevention
 

Steriflow Valves

Features & Benefits:

  • Removal of tranditional spring and guide:
  • Eliminates area where bioburden and bacteria can accumulate 
  • Potential for particulate generation 
  • Very low cracking (opening) pressure 
  • High flow rates with minimal pressure loss at increased flow compared with mechanical return check valves
