Steriflow SHC Series Sanitary Check Valves

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

  • WFI loop: non-return at pump out
  • Media/buffer prep: back flow prevention during dilution
  • Upstream process: sparge line back flow prevention
  • Separation: centrifuge waste line back flow prevention
  • Purification, chromatography: waste line back flow prevention
  • Pump head pressure maintenance or pressure bypass
  • F & B and consumer H & B process inputs, outputs, purified water and clean utility back flow prevention
 

Steriflow Valves

Features & Benefits:

  • Removal of traditional spring and stem guide:
  • Eliminates areas where bioburden and bacteria can accumlate
  • Potential for particulate generation 
  • No hold up 
  • High flow rates with minimal pressure loss an increased flow compared with mechanical return check valves. 
  • Very low cracking (opening) pressure
