As critical safety equipment in laboratories, chemical workshops, and other similar settings, fume hoods' core function is to rapidly exhaust harmful gases, dust, and other pollutants, protecting the health of operators. Venturi valves, with their high-precision flow control and rapid response characteristics, have become an ideal component for fume hood exhaust systems. They can respond in real-time to airflow fluctuations caused by fume hood door opening and closing, internal operations, ensuring stable negative pressure within the hood, preventing pollutant leakage, and simultaneously achieving energy efficiency. This addresses the industry pain points of traditional valves, such as delayed response and excessive energy consumption.
