Abstract of the Disclosure An improved glandless plug valve of the type in which a tapered plug fits into a tapered bore in a valve body is provided wherein the tapers formed on the plug and in the body coact to form a body seal. A stem seal is also provided. The stem seal comprises a ring-like sealing member confined within mating grooves in the top of the plug and in a floating seal member. The floating seal member is biased downwardly to effect the seal between itself and the ring-like seal member. The bias force is transmitted to the plug valve urging it into engagement with the body of the valve, to provide a good body seal. In a preferred embodiment, the valve and plug are lined such that the valve is suitable for use in connection with corrosive liquids or slurries. The floating seal provides automatic compensation for temperature induced dimensional changes and for wear.
