A plug valve is disclosed which has a radially outwardly directed projection at the end of the valve stem, the projection being received in a complementary cylindric chamber in the plug of the valve for easy exchange of the plug during maintenance of the valve. The plug is freely rotatable relative to the stem of the valve. In the preferred embodiment, the stem of the valve does not rotate during the opening or closing motion. The invention provides a simplified structure, improves reliability of the valve and the simplicity of exchange of the plug in maintenance.
