Primarily blocks the airflow within the system for room sterilization and airtight isolation of the environment.

Shanghai KuaiLi Company collaborates with European partners in the research, development, and production of bio-safe electric sealed valves. These valves are used in high-risk bio-safety applications such as air isolation in nuclear power plants and highly hazardous biological laboratories. The sealed valves are commonly employed in the disinfection of bag-in-bag-out filters and the shutdown of ventilation pipes in bio-safety level 3 and 4 laboratories, facilitating room disinfection and environmental sealing and isolation.

Biological sealed valves are divided into two types: air flow blocking and air volume regulating. They also come in two shapes: round valves and square valves. Specific dimensions can be customized according to actual air volume requirements and on-site layout.

I. Product Advantages

1. Utilizes high-density EPDM seals for enhanced corrosion and oxidation resistance.

2. The structure features an integrated design, ensuring reliable product strength.

3. Fewer weld joints, lower risk.

II. Technical Specifications

1. The bio-safety sealed valve, in its initial operating state, has an hourly leakage rate not exceeding 0.25% of the device's net volume when the working pressure is no less than ±2500Pa.

2. After the valve has been opened and closed continuously 5,000 times, and when the working pressure is not less than ±2,500 Pa, it still ensures no leakage in the positive and negative pressure working state within at least 60 minutes.

3. Customizable explosion-proof biological sealed valve.

4. Larger sizes include circular diameters of 1200mm and square dimensions of 2500mm x 1200mm. (For larger sizes, non-standard dimensions are available for custom orders.)
