FIELD: machine engineering.

SUBSTANCE: invention relates to the flow control valve (1) for liquid heating and cooling installations, consisting of housing (2) having an inlet (3) and an outlet (4) and a connecting pipe (13) located between them wherein a pressure control device (14) is inserted which supports constant pressure differential between pressure ranges in front of and behind the flow control unit (8) located in the connecting pipe, as well as a spindle (7) having a control element protruding from the housing (2) and the first throttle element (9) located in the housing (2) which affects the flow control unit or its parts. This flow control unit (8) consists of the first throttle device which is formed from the first throttle element (9) fixed on the spindle (7) and a seat (10), and the second throttle device which is formed from the second throttle element (11) mounted on the spindle (7) with the possibility of longitudinal relocation on it and a seat. The second throttle element (11) is movable in the direction of the first throttle element (9).

EFFECT: valve has a simpler design and takes up less space.
