Low flow, Jorlon diaphragm

Angle style control valve for continuous precision low flow control of media, process, purified water and clean utilities in the biopharmaceutical, pharmaceutical, food & beverage and consumer health & beauty industries:

  • Small bioreactor/fermenter process input control: growth media, WFI, process sparge and blanket gas
  • Separation input and output control: WFI, process, product & waste streams
  • Small vessel formulation/fill control: WFI and other vessel inputs, blanket gas, dosing pressure
  • Purification input and output control: Elution media, solvents, buffer, WFI
  • Clean utilities: USP PW (purified water), WFI, pure steam, CIP, clean compressed air and gas
  • F & B and Consumer H & B Process: inputs, outputs, purified water and clean utilities
Features & Benefits
  • The smallest nominal flow offering in the industry. Six Cv’s between 0.005 and 0.1 enables you to control flow for any application
  • Maintenance friendly – quick change trim simplifies disassembly, reassembly, and steam-in-place/clean-in-place capabilities
  • Mechanically and electropolished internal components – 20Ra (0,5µm) finish; others upon request
  • FDA and USP Class VI conformity on all process seal materials
  • Gravity draining/no holdup and a variety of installation orientations
  • Size: 1/2″ & 3/4″ (DN15 & DN20)
  • End Connections: ASME, DIN and ISO tri-clamp, extended tube weld
  • Cv (Kv) & Flow Characteristic: 0.005 – 0.1 (0,0034 – 0,086) linear or equal percentage trim
  • Max Pressure: 200 psi (13,8 bar) temperature dependent on o-ring construction
