Flow control devices.- In a general embodiment, the present disclosure provides a cassette (30) comprising a housing having a flow restrictor (34), and a tube (36) attached to the housing and positioned adjacent the flow restrictor. The flow restrictor may be so constructed and arranged to rotate from a first position in which the flow restrictor prevents fluid flow through the tube to a second position in which fluid is able to flow through the tube when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.
