What kind of duct valves are required in the exhaust duct and near the fan?
Air volume control valve is the industrial plant civil construction ventilation, air conditioning and air purification works indispensable central air conditioning end fittings, generally used in air conditioning, ventilation system pipes, used to adjust the amount of air flow, can also be used for fresh air and back Mixed with wind.
Through the test, the air volume regulator valve air tightness is good, the relative leakage of about 5%, good regulation
The air flow control valve blades are open and open, and are used as control valves in ventilation, air conditioning and air purification systems.
The size of the multi-leaf air volume control valve is the same as that of the rectangular duct of the national ventilation duct.
Mechanical exhaust system due to the fan as a power, can effectively control and distribution of air volume (which is the biggest difference with the natural ventilation), so the system piping (ie duct) need to set the air volume control valve.
