An extrusion system, for example for extruding a food product, that includes: an extruder, which propels extrudate through an outlet of the extruder; and a valve. The valve includes: an inlet, which receives extrudate from the extruder outlet; a main conduit, which extends from the inlet to a main outlet; a dumping conduit, which extends from a junction with the main conduit to a dumping outlet; and a flow control member, which is operable to move between: a plurality of flow controlling positions, in which extrudate is directed to the main outlet, with the flow control member providing, for each flow controlling position, a respective amount of impedance to flow along the main conduit; and a flow diverting position, in which extrudate is directed along the dumping conduit to the dumping outlet.
