When the pressure difference between the front and rear ends of the venturi valve is changed (applicable to the pressure variation range of 150-750Pa), it can automatically balance the pressure fluctuation and automatically in one second. To the set air volume value while maintaining the set air volume value without being affected by the pressure difference change. The self-excitation control shall ensure that the error range is within ± 5% of the set air flow value.
Features: 
Pressure independent operation: Self-adjusting mechanical components, air volume and pipeline pressure change has nothing to do, in the system changes, filter blockage, HVAC system performance deterioration of the case to maintain a stable flow.
Factory calibration: according to the actual situation of air flow requirements, calibration provisions of the air volume value
Adjustment ratio: In the range of air flow value has 20 adjustable opening.
Air volume calibration: the air volume in the factory calibration.
Flexible installation position: no direct pipe valve interface requirements, there are vertical and horizontal installation type valves.
Installation and commissioning is simple, maintenance-free.
