The biosafety airtight valve/air seal valve, also known as the low leakage valve and biosafety airtight valve, can divide the ventilation system into several zones and is applied in nuclear power, petrochemical, food processing, laboratories, and other places. It has good air tightness and can meet the safety requirements of zero leakage in special occasions (achieving zero leakage under a specified pressure difference). The typical application of the biosafety airtight valve/air seal valve is as an isolation filter and contaminated component in the BIBO system.
Product Application

Technical Features
The airtight valve is divided into manual and electric types based on different actuators. The electric airtight valve can be paired with an automatic control system to automatically control and adjust air volume, ensuring its airtightness even in the event of power failure. The material and size of the valve body can be customized according to the actual needs of customers. It meets the American ASME N509 or European Union EN12266-2 standards, achieving zero leakage at a pressure difference of 10 inches of water column (2500Pa). It can also meet the safety requirements of zero leakage (zero leakage at a specified pressure difference) in special situations.
