1. Pharmaceutical and biological fermentation process control. Pneumatic actuators play a key role in the production process that requires sterility and high cleanliness:
Aseptic filling and flow regulation: In the aseptic filling line of vaccines or drugs, sanitary grade pneumatic diaphragm valves combined with pneumatic actuators can achieve precise flow control and support online CIP/SIP cleaning, greatly reducing the risk of microbial contamination.
Fermentation tank parameter regulation: Combined with high-precision locators and pH sensors, pneumatic control valves can adjust the pH value in the fermentation tank in real time, effectively improving the conversion rate of fermentation broth and batch stability.
● Liquid dispensing system transportation: Pneumatic double seat valves with oil-free lubrication design are used for controlling the transportation of sterile water and drug solutions, avoiding contamination of the medium by lubricating oil and ensuring the purity of the drugs.
● Reactor discharge control: Pneumatic discharge valves (as shown in the above expansion structure) are widely used in the bottom of reaction vessels in biopharmaceuticals to achieve precise discharge of materials and are not easily blocked by sediment.

2. Cleanroom and environmental airflow management - Biochemical laboratories and production workshops have strict environmental requirements, and pneumatic dampers are indispensable in such scenarios:
Pressure and airflow organization: Pneumatic dampers are used to maintain a positive/negative pressure environment in clean rooms and accurately control particle concentration; Simultaneously applied to the airflow control of fume hoods and biosafety cabinets to ensure operational safety.
Process exhaust and odor treatment: During food processing or biochemical reactions, pneumatic air valves are responsible for regulating the airflow of the drying system, collecting exhaust gases, and controlling odors.

3. High purity media and special material transportation. For media with corrosive or extremely high purity requirements, pneumatic valves made of specific materials demonstrate excellent performance:
Ultra high purity fluid control: In semiconductor related or high-end biopharmaceutical production, high-pressure pneumatic high-purity diaphragm valves achieve minimal particle generation and zero dead zone with their extremely small internal volume and fully enclosed valve seat design, meeting the distribution needs of ultra pure reagents.
Corrosive liquid merging and diversion: Pneumatic UPVC three-way valves utilize their excellent corrosion resistance and are widely used in the transportation and flow switching of liquid containing corrosive chemicals, ensuring long-term stable operation of equipment.

4. In addition to directly participating in the production process, pneumatic actuators also extensively serve the infrastructure of factories for public works and auxiliary systems
Temperature and steam control: The pneumatic temperature regulating valve installed on the steam inlet pipeline of the drying equipment can automatically adjust the opening according to feedback signals to ensure the temperature stability of the drug drying process.
Water treatment and purification system: In the reverse osmosis system used for preparing purified water in pharmaceutical factories, mirror polished stainless steel porous pneumatic control valves are used for high-precision flow control. In addition, in the sludge discharge and wastewater management of water treatment, equipment such as pneumatic clamp ball valves have also achieved remote automation management.
