In demanding environments such as pharmaceutical workshops, electronic cleanrooms, biological laboratories, and precision testing rooms, stable airflow, precise airflow control, and pressure self-adaptation are crucial for ensuring environmental compliance. Venturi valves, as core airflow control components in HVAC and cleanroom ventilation systems, have become the mainstream choice for variable air volume (VAV) systems and FFU (Fan Filter Unit) systems due to their self-regulating structure, high-precision adjustment, and low pressure loss.
