The flow regulator for air-conditioning systems comprises a housing (1) defining an inner space with an air passage section; at least one sealing element (4) movable between an open and closed position and vice versa, according to which the air passage section of the inner space is determined; and a divider (2) located inside the housing (1), which divides the inner space into two channels (3).
It allows avoiding or minimizing noise generation, reducing the minimum pressure drop of the regulator, reducing energy consumption, and also improving the accuracy of the measurement system at low flow rates.
