Product description

Angle style, back pressure reducing valve for purified water, clean utilities and media in the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries.


Applications

  • WFI distribution loop: return loop pressure maintenance upstream of spray ball
  • Media/buffer prep., upstream process
    - input back pressure control for mixing buffer, media
    - pressure maintenance and relief to sterile containment
  • Separation input and output control: for perfusion TFF, for Trans-membrane Pressure (TMP) control
  • Purification input and output control: for chromatography column, TFF or depth filtration differential pressure control
  • Pump head pressure maintenance or pressure bypass
  • Agitator or pump seal water pressure maintenance
  • F & B consumer H & B process inputs outputs, purified water and clean utilities

  • Jorlon FDA, USP Class VI, 316L, EPDM/Nylon (FDA only)
Soft Seat Option
  • Jorlon, PEEK, Teflon (all materials FDA, USP Class VI)
Features and Benefits
  • No guiding surfaces in the fluid – minimizes particulate generation
  • Soft seat option for ANSI Class VI shutoff
  • 100% 316L barstock body and trim
  • Low offset (creep)
  • Lifetime warranty of Jorlon diaphragm
  • New integral gauge ports optional
  • Removing spring force during Rinse/CIP/Rinse cycle allows valve to fully open with minimal line pressure
  • LL Option allows users to manually open the valve to allow for complete drainability without affecting the set point.
