Valves play a key role in the pharmaceutical industry, where applications require high hygiene standards, sterile environments, precise control, and compliance requirements.

 

Applications of valves in the pharmaceutical industry

 

I. API production

a. Reaction and synthesis system

- Applications: medium delivery (acid, alkali, organic solvent) and catalyst control of chemical synthesis reactor.

 

b. Crystallization and drying

- Applications: crystallization reactor feeding and discharging, vacuum drying system.

 

II. Biopharmaceuticals and fermentation

a. Fermentation tank system

- Applications: culture medium delivery, fermentation liquid discharge, sterile air/gas control.

 

b. Cell culture and purification

- Applications: bioreactor feeding, chromatography column buffer control.

 

III. Preparation production and filling

a. Liquid preparation system

- Applications: drug solution mixing, water for injection (WFI) delivery.

 

b. Filling line

- Applications: liquid/lyophilized powder packaging, sterile environment control.

 

c. Freeze dryer system

- Applications: condenser control during vacuum freeze drying.

 

IV. Purified water and cleaning system

a. Pure water/water for injection (PW/WFI) system

- Applications: water treatment circulation, distribution pipelines.

 

b. CIP/SIP system

- Applications: online cleaning and sterilization of acid and alkali liquids, steam pipeline control.

 

V. Public works and environmental protection

a. Clean gas system

- Applications: compressed air, nitrogen, oxygen supply (such as sterile air for fermentation).

 

b. Wastewater and waste gas treatment

- Applications: wastewater treatment containing organic solvents, VOCs recovery.
