Biological Safety Airtight Valve
Filtration Grade / Efficiency: Not applicable (valve product, not a filtration product)
Specifications / Dimensions: Nominal diameter DN150～DN1000 (DN150/200/250/300/400/450/500/630/700/800/850/900/1000)
Rated Air Volume: selected by nominal diameter
Other Key Parameters: Airtightness pressure decay test: leakage rate per minute ≤0.2% of the sealed container net volume at ±2500Pa; airtightness still meets requirements after 10,000 continuous open/close cycle tests; operation modes: manual, electric, pneumatic
Product Configuration (Material / Structure, etc.): Cylindrical housing; sealing valve plate composed of SUS304 stainless steel plate and high-quality silicone gasket (gasket replaceable, resistant to compression set and creep); lock nuts connecting 2 SUS304 plates with silicone gasket; welded design, all pressure-holding welded joints continuously fully welded, welds wire-brushed or polished; actuator can be equipped with electric or manual; material SUS304; surface treatment: brushed, sandblasted
DETAILS INTRODUCTION
Product Features:
Biosafety protection airtight shut-off valve: after closing the valve disc, the air filtration system can be shut off, serving as a key sealing device to block harmful gases from entering or being discharged to other areas; cylindrical housing design greatly minimizes disinfection blind spots, allowing disinfectant to fully contact the valve body and ensuring disinfection effectiveness; can divide the ventilation system into several zones with good airtightness, meeting zero-leakage safety requirements in special occasions (zero leakage at specified differential pressure); all-stainless-steel welded structure with excellent corrosion resistance.
Applications:
BSL-3/4 laboratories involving highly pathogenic pathogen handling, high-level ABSL, negative pressure isolation wards, high-risk biopharmaceutical production lines; ventilation system zoning in nuclear power, petrochemical, food processing, laboratories, and other facilities.
