Ventilating valve for plastic windows: types, installation, reviews



Vent The valve for a plastic window is a part of a narrow oblong shape with small openings through which air passes. The device has several modes of operation, which are selected depending on the difference in temperature, humidity in the street and at home.

Adjustment of the work of the air vent on some models is done manually with a cord (like a blind). Other valves are regulated by the valve (the leftmost position opens the flow of air, the rightmost one closes it).

Automatic tuning works as follows. The mode of operation depends on the flow of air pressing on the curtain with a suspension that rises and falls depending on the strength of this pressure.

Some ventilation valves have sensors that increase or decrease the cross-section of the hole, depending on the humidity in the room.
