1. The ventilation control valve is suitable for fresh air transmission, waste gas emission and air purification projects in ventilation and air conditioning systems in industrial plants and civil buildings. It can not only adjust the style and quantity, but also close it. The test shows that the air tightness of the regulating valve is good, and its relative air leakage is no more than 5%

2. The regulating valve is divided into manual and electric. The cross-section size of the valve is made according to the size of the national ventilation standard air duct. Manual handle type and hand wheel type. The insulation type regulating valve is provided with a 35 mm thick insulation layer on the inner side of the connecting rod.
