  • Bioreactor/fermenter: sparge gas, purge/blanket/motive force gas regulation
  • Separation: purge/blanket/motive force gas regulation for process vessels
  • Purification: purge/blanket/motive force gas regulation for process vessels
  • Formulation: purge/blanket/motive force gas regulation for proves vessels
  • Lyophilization: purge/blanket/motive force gas regulation for process vessels
  • Clean utility: CGG (clean compressed gas) pressure control for post SIP drying of small vessels, tubing, filters, etc.
  • F & B consumer H & B process: purge/blanket/motive force gas regulation
Features & Benefits
  • Proprietary Jorlon diaphragm provides exceptionally long life
  • Top entry design facilitates in-line cleaning and maintenance
  • Low lock-up with EPDM seat
