  • Small stainless steel or single use disposable bioreactor/fermenter, sparge gas, purge/blanket/motive force gas regulation and bag integrity testing
  • Separation: purge/blanket/motive force gas regulation and bag integrity testing
  • Purification: purge/blanket/motive force gas regulation and bag integrity testing for process vessels
  • Formulation: purge/blanket/motive force gas regulation and bag integrity testing for process vessels
  • Lyophilization: purge gas regulation
  • F & B consumer H & B process purge/blanket/motive force gas regulation
Features & Benefits
  • Stable outlet pressure setpoint regulation as low as 1 psig (68 mB)
  • Top entry design facilitates in-line cleaning and maintenance
  • Barstock construction guarantees material integrity and quality surface finish
  • Four Cv’s from 0.01 to 0.2 guarantee an application fit
  • Large, proprietary Jorlon diaphragm provides exceptionally long life and sensitivity to minimal pressure changes
  • Low lock-up with EPDM seat

Note: These valves may be used on non-cavitating liquid, or clean steam applications. However, they are not drainable. Steriflow Engineering must review application before acceptance.
