Product description
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
Applications
- 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
