Abstract: A flow control valve has a body defining a cavity therein, a first and second outlets, a first and second inlets, and a modulating body disposed at least in part in the cavity. The modulating body is pivotable in: a) a first range of angular positions, in which the modulating body fluidly connects the first outlet to the first inlet and blocks the second opening and the fourth opening; b) a second range of angular positions, in which the modulating body fluidly connects the second outlet to the second inlet and blocks the first and the third opening; c) a third range of angular positions, in which modulating body fluidly connects the first outlet and the second outlet to the second inlet and blocks the third opening; and d) a fourth position, in which the modulating body blocks the third opening and the fourth opening.

Abstract: A flow control valve comprises three orifices. Each of the three orifices is connectable to a fluid conduit, respectively. Each of two orifices of the three orifices is modulatable between a closed mode in which that orifice is substantially closed, and an open mode in which that orifice is open. Each of the two orifices is also modulatable between the closed mode and the open mode while the other one of the two orifices is in the closed mode. Depending on the application, the orifices may be used as inlets or outlets and in different combinations of inlets and outlets. A hydronic system that includes the flow control valve is also described.
