ABSTRACT OF THE DISCLOSURE A pivotal disc shut-off valve is disclosed wherein a disc is pressed against a peripheral seat within a valve body to halt the flow of fluid material in a flow line. The disc is operated by a system of linkage arranged so as to allow the disc to be linearly moved in relation to the seat as a separate and distinct motion from pivotation of the disc. In closing the valve, a provision is made by which the disc is rocked as it contacts the seat to insure full closure. All motions of the disc are positively directed, with no reliance on the force of gravity, thus allowing the valve to be used in all positions.
