Abstract
In a plug valve with a plug supported around its axis of rotation in a flow passageway of the valve housing, the plug is supported in a floating manner against a spring force pressing the plug against an annular sealing element. The spring force is provided by a spring element bearing against the valve housing and engaging with a trunnion of the plug. The sealing element is supported in a fixed position against a flow passage opening.
