ABSTRACT:
A rotary plug valve has a frusto-conical valve plug (4) received within a frusto-conical valve chamber with a tapered valve liner (3) being provided between the two. The chamber and the plug are oppositely tapered so that by axial movement of the plug the valve liner can be wedged into tight sealing engagement with the external surface of the valve plug and the internal surface of the valve chamber. The liner and the valve plug are insertable and removable as a unit from the frusto-conical chamber.
