Airtight valve
Shanghai Jiehao Biotech specializes in the production of high-quality biosafety airtight valves, which are essential for maintaining the integrity of air conditioning and ventilation systems in various critical environments. These valves, also known as low leakage valves, are designed to effectively block airflow within the supply or exhaust pipes, ensuring optimal air tightness and safety .
Our biosafety airtight valves are meticulously crafted to meet the highest industry standards, providing reliable performance in applications such as nuclear power, petrochemical, food processing, and laboratory settings. Each valve undergoes a rigorous zero-leak test before leaving our factory, guaranteeing their reliability and quality.
According to the ISO10648-2 "Isolator-Air Tightness Classification and Related Test Methods" and GB 50346-2011 "Technical Specification for Biosafety Laboratory Construction", it can be divided into round and rectangular according to the different needs of users.
Standard
- Biosafety Laboratories: A key component in BIBO systems for isolating filters and contaminants.
- Nuclear Power Plants: Ensuring high safety standards for ventilation systems in nuclear facilities.
- Petrochemical Industry: Suitable for harsh chemical processing environments, ensuring system safety.
- Food Processing: Maintaining hygiene and safety standards in food processing environments.
Application Fields
● Air tightness: Under the pressure of ± 2500pa, the leakage rate per hour shall not exceed 0.25% of the net volume.
● Pressure-bearing capacity: The valve box has no permanent structural deformation before and after bearing -2500pa pressure for 60 minutes.
● Service life: the valve opening and closing 10000 times after the test of air tightness, positive pressure, negative pressure air tightness in line with national standards.
● Corrosion resistance: all parts of the valve are resistant to hydrogen peroxide, chlorine dioxide, formaldehyde and other disinfectants. After corrosion test, the air tightness still meets the requirements of national specifications.
● Resistance: In the case of rated air volume and valve fully open, the resistance shall not exceed 40Pa.
