Structure principle
Electric air flow control
Suitable for supply or exhaust air
The air volume range is about 5∶1
Differential pressure range 20 to 1000 pa
The precision of air volume control is high. Ensure that the layout of air ducts meets the optimal airflow characteristics
The air volume is set or programmed before delivery, and the air performance of each device is tested on the calibration table. Relevant parameters are identified on the test label attached to each device
Re-measure or set air volume value on site if necessary
Mount horizontally or vertically
Air valve can be closed completely
The tightness of THE VAF valve disc is good when closing, and the air leakage rate is not more than 5℅
The regulator is a mechanical component that requires no maintenance
