Biosafety Sealed Valve: An innovative technology to protect a biosecure environment

In today's era of rapid technological change, biosecurity has become an important link that cannot be ignored in various scientific research fields and production links. In order to ensure the safe operation of high-risk environments such as biological laboratories, pharmaceutical factories, and medical facilities, an innovative device called the "Biosafety Sealed Valve" was developed. This article will introduce the advantages and performance parameters of biocontainment valves in detail, revealing their important role in biosafety environments.

Performance parameters

In terms of performance parameters, the Biosafety Sealed Valve performs exceptionally. It has a wide range of working pressure, which can withstand the working pressure of plus or minus 2500Pa, ensuring stable operation in a high-intensity working environment. At the same time, the leakage rate of the valve is extremely low, and in the initial working condition, the hourly leakage rate does not exceed 0.25% of the net volume of the unit. Even after 5000 consecutive opening and closing of the valve, it can still maintain a leak-free state for at least 60 minutes at a working pressure of plus or minus 2500Pa, fully demonstrating its excellent durability and reliability.

The unique design of the QUALIA Biosafety Sealed Valve is the use of a split opening and closing of the valve blades, an innovative design that ensures that the valve is both efficient and precise in its closing action. High-quality rubber seals are installed between the valve body and the valve vanes, as well as at the junction of the adjacent valve vanes, which are molded through a precision molding process to ensure the valve's excellent sealing performance.

Easy to operate

In order to improve the ease of operation, one side of the valve is cleverly equipped with a flexible manual (electric) adjustment mechanism. The two ends of the valve blade are tightly connected to the valve body by a precision square shaft and copper sleeve, and are equipped with a transmission link. After installation, these connecting rods are covered by a connecting rod guard, which not only effectively protects the connecting rods, but also greatly improves the overall aesthetics of the valve.

The design of the connection between the adjusting mechanism and the square spindle has been carefully considered to ensure the accuracy and stability of the adjustment process. The valve body, valve blades and connecting rod guards are made of flowerless galvanized sheet, which not only provides excellent corrosion resistance, but also ensures the strength and durability of the valve. Among them, the thickness of the galvanized layer reaches 80 grams, which provides a solid guarantee for the long-term use of the valve.

Material selection

Biosafety Sealed Valves have also put a lot of effort into the selection of materials. The valve body, valve blade and connecting rod guard are made of flowerless galvanized sheet, which not only has good corrosion resistance, but also ensures the strength and durability of the valve. The thickness of the galvanized layer reaches 80 grams, which further increases the corrosion resistance of the valve. At the same time, key metal fittings such as square shafts and transmission connecting rods have also been galvanized to prolong the service life of the valve.

Fields of application

In terms of application fields, Biosafety Sealed Valves are widely used in ventilation duct systems in high-risk environments such as biological laboratories, pharmaceutical factories, and medical facilities. It can not only support the disinfection process of bag-in-bag-out filters, ensure the reliable shutdown of ventilation ducts in biosafety level 3 and 4 laboratories, but also effectively prevent the spread of harmful microorganisms such as viruses and bacteria, and provide a strong guarantee for the health and safety of researchers and patients.

Conclusion

Biosafety Sealed Valves have become indispensable and important equipment in biosafety environments due to their excellent sealing performance, stable working performance, flexible operation performance and high-quality material selection. With the continuous progress of science and technology and the increasing awareness of biosafety, the application prospect of Biosafety Sealed Valve will be broader. We look forward to this innovative technology continuing to contribute to the development of biosafety."
